Question

Fuel wood is measured in cords. The number of cords in a pile l ft long, w ft wide, and h ft tall can be estimated using the equation number of cords=lwh128 .

Ben measures a pile of wood to be 8 ft long by 32 ft wide.

Which equation can be used to determine the number of cords in a pile of wood h ft tall?

A. number of cords=128h256

B. number of cords=256h128

C. number of cords = 128h

D. number of cords = 256h

Answer 1

Number of cords=
`256h128`

Explanation:

Given : Ben measures a pile of wood to be 8 ft long by 32 ft wide.

To Find: Which equation can be used to determine the number of cords in a pile of wood h ft tall?

Solution:

The number of cords in a pile l ft long, w ft wide, and h ft tall can be estimated using the equation:

Number of cords=
`lwh * 128`

Now we are given that length of wood = 8 ft

Width of wood = 32 ft.

So,
`l * w = 8 * 32 =256`

Substitute the value in the equation .

So, Number of cords=
`256h128`

So, Option B is correct.

Hence The equation can be used to determine the number of cords in a pile of wood h ft tall is Number of cords=
`256h128`
