Building Noah's Ark

Genesis 6:15-16
"And you shall make it this way: The length of the ark shall be three hundred cubits, its breadth fifty cubits, and its height thirty cubits." — God gave Noah precise dimensions for the vessel that would preserve life through the Flood. Let's calculate just how massive this structure was.
0 / 5 steps
1
The ark was 300 cubits long. Convert to feet (1 cubit = 1.5 ft).
2
The ark was 50 cubits wide. Convert to feet.
3
The ark was 30 cubits high. Convert to feet.
4
Calculate the total volume in cubic feet (450 × 75 × 45).
5
The ark had 3 decks. What's the area of one deck? (450 × 75)

Scripture Connection

That's about 569 standard railroad boxcars — enough room for thousands of animals, food, and supplies. God's engineering specifications were more than sufficient for the task!

Solomon's Temple Dimensions

1 Kings 6:2-3
"As to the house that King Solomon built for Jehovah, its length was sixty cubits, its breadth twenty, and its height thirty cubits." Solomon's magnificent Temple was the crowning achievement of ancient Israel — let's discover its true size.
0 / 5 steps
1
The temple was 60 cubits long. Convert to feet (1 cubit = 1.5 ft).
2
It was 20 cubits wide. Convert to feet.
3
It was 30 cubits high. Convert to feet.
4
Calculate the floor area in square feet (90 × 30).
5
The porch was 20 cubits long and 10 cubits wide. What's its area in square feet? (30 × 15)

Scripture Connection

Solomon's temple was about the size of a modest church — roughly 2,700 sq ft. Its glory was in its extraordinary craftsmanship and materials — gold, cedar, and carved cherubim — not its sheer size.

Feeding the 5,000

John 6:1-13
Jesus took five barley loaves and two fish from a boy's lunch and fed a multitude. "And when they were filled, He said to His disciples, Gather up the fragments left over, that not anything be lost." Let's explore the mathematics of this miracle.
0 / 4 steps
1
Jesus started with 5 loaves and 2 fish. How many food items total?
2
5,000 men were fed. If each family averaged 4 people, estimate the total crowd.
3
If each person ate about 0.5 lb of food, how many total pounds were consumed?
4
They collected 12 baskets of leftovers. If each basket held 5 lbs, how many pounds leftover?

Scripture Connection

From 7 items came enough to feed ~20,000 people with 60 lbs to spare — the mathematics of divine provision. God's economy doesn't just meet needs; it overflows.

The Tabernacle Courtyard Curtains

Exodus 27:9-18
"And you shall make the court of the dwelling place of God; for the south side southward, hangings for the court of twined linen, a hundred by the cubit in length… And so for the north side in length, hangings a hundred in length… And the width of the west side of the court shall have fifty cubits of hangings… And the width of the court for the east side eastward fifty cubits." God prescribed the exact curtain dimensions for His dwelling place among the Israelites.
0 / 5 steps
1
South side: 100 cubits of curtain. Convert to feet (1 cubit = 1.5 ft).
2
North side: also 100 cubits. Convert to feet.
3
West side: 50 cubits. Convert to feet.
4
East side: 50 cubits total, but the gate was 20 cubits. How many cubits of curtain on each side of the gate?
5
Total curtain length (all sides, not counting the gate): 100 + 100 + 50 + 30 = ?

Scripture Connection

280 cubits of fine linen — a massive undertaking in the wilderness, woven and erected by hand, all to create a sacred space for God's presence among His people.

The Parable of the Talents

Matthew 25:14-30
"And to one indeed he gave five talents, and to another, two, and to another, one, to each according to his ability." Jesus taught about faithful stewardship through this parable of investment and return. Let's do the math.
0 / 5 steps
1
The master gave 5 talents to Servant A, 2 to Servant B, and 1 to Servant C. Total talents distributed?
2
Servant A doubled his talents. How many does he now have?
3
Servant B doubled his. How many does he have?
4
Servant C buried his. How many does he still have?
5
What is the total return? (All servants combined: 10 + 4 + 1 = 15, minus original 8)

Scripture Connection

87.5% return from the faithful, 0% from the fearful. God measures faithfulness, not the starting amount. "Well done, good and faithful servant!"

Nehemiah's Wall

Nehemiah 6:15
"And the wall was completed in the twenty-fifth of Elul, on the fifty-second day." Against all opposition, Nehemiah led the rebuilding of Jerusalem's walls — a feat of engineering and faith. Let's verify the math behind this miracle of organization.
0 / 5 steps
1
The wall was completed in 52 days. How many weeks is that? (Round to 1 decimal place)
2
The wall was approximately 2.5 miles around. Convert to feet (1 mile = 5,280 ft).
3
If the wall averaged 40 ft high and 8 ft thick, what's the cross-section area per foot of length?
4
Total volume of wall in cubic feet (13,200 × 320).
5
If workers moved 1,000 cu ft of stone per team per day with 80 teams, how many cu ft per day total?

Scripture Connection

At 80,000 cu ft/day, the 4.2 million cu ft wall would take 52.8 days — remarkably close to the biblical 52! The math confirms the historical account of this extraordinary achievement.
