Question

A concrete foundation for a building has the shape of a rectangular prism. the foundation is 14 yards long, 12 yards wide, and 2 yards

high. if concrete costs $4 per cubic yard, how much did the concrete cost for the foundation?

Answer 1

$1,344.00

Explanation:

Volume = Length x width x height

Volume = (14)(12)(2)

Volume = 336
`yd^(3)`

To find the cost we multiply the volume by the cost per cubit yard.

336(4) = 1344

Answer 2

$ 1344

Explanation:

Volume of rectangular prism:

l = 14 yards

w = 12 yards

h = 2 yards

`\sf \boxed{\bf Volume \ of \ rectangular \ prism = l*w*h}`

= 14*12*2

= 336 cubic yards

To find the cost, multiply the volume by the rate per cubic yard.

Cost = 336 * 4

= $ 1344
