Dirt must be removed for the foundation of a building that is 30 yards by 18 yards with a depth of 4.5 yards. If a truck has a capacity of 3 cubic yards per load, how many truckloads of dirt are necessary?

a) What is the volume in cubic yards?
I put 2430 cubic yards

b) How many truck loads of dirt will be removed?
would it be 810, 3/2430

correct on both.

a) To find the volume in cubic yards, you need to calculate the length, width, and depth of the foundation and multiply them together.

Given:
Length = 30 yards
Width = 18 yards
Depth = 4.5 yards

Volume = Length × Width × Depth
Volume = 30 yards × 18 yards × 4.5 yards
Volume = 2430 cubic yards

So, you are correct. The volume is 2430 cubic yards.

b) Now, to calculate the number of truck loads of dirt that will be removed, you need to divide the total volume by the capacity of each truck load.

Given:
Truck capacity = 3 cubic yards

Number of truck loads = Volume ÷ Truck capacity
Number of truck loads = 2430 cubic yards ÷ 3 cubic yards
Number of truck loads = 810

So, you are correct again. You will need 810 truck loads of dirt to remove the necessary amount of dirt for the foundation.
