Answer:
480 ft^3
Explanation:
We can calculate the volume of the sculpture with the data they give us in the statement.
The volume would be the multiplication between the length, width and height, that is:
v = l * w * h
we know that l = 12 ft; w = 5 ft; h = 8 f, replacing:
v = 12 * 5 * 8
v = 480
in other words, the volume of the sculpture is 480 cubic feet, therefore 480 color blocks are needed because its volume is 1 cubic foot.
