How many cubic yards of dirt must be removed when digging a foundation for a building if the excavation is 94 ft. long and 36 ft. wide and 24 ft. deep?

We have to calculate how many cubic yards of dirt must be removed. First we have to convert feet to yards:

1 yard = 3 ft

L = 94 ft : 3 = 31.33 yd

W = 36 ft : 3 = 12 yd

H = 24 ft : 3 = 8 yd

Volume:

V = L x W x H = 31.33 * 12 * 8 = 3,008 yd³

Answer : 3,008 yd³.
