1 cubit = 1.5 frrt so 1.5 cubit feet = 2.25 square feet.
10' x 15' x 8' = 1,200 cubic feet.
13' x 15' (195 square feet) = 21.67 square yards of carpet needed.
25.33 yards
45 feet is 15 yards.
80 square feet x 15 = 1200 square feet.
10' x 15' x 8' = 1,200 cubic feet.
Cubic yards are a measure of volume. 58.67 yards is 176.01 feet. 15 mph is 22 feet per second. You will cover that distance in 8 seconds.
You would need 20 square yards of carpet which is 180 square feet.

the length of a cubit was measured as fingertips to elbows, now taken as 18" thus 3000 cubits is 2000 feet3000 cubits = 4500 feet
15 x 14 is 210 square feet. If one box is 45 square feet, you'll need 5 boxes.
How much area would 15 bundles of shingles cover. Standard duty shingles use 3 bundles for every 100 square feet so 15 bundles would cover 500 square feet.
