Question

Jenny has two congruent kleenex boxes. The first box has a volume of 72 in2, a length of 3 inches and a width of 4 inches. What is the height of the second box?

Answer 1

The height of the second box is
`6\ in`

Explanation:

we know that

If the two boxes are congruent

then

The volume of the first box is equal to the volume of the second box

The length of the first box is equal to the length of the second box

The width of the first box is equal to the width of the second box

The height of the first box is equal to the height of the second box

so

Find the height of the first box

Remember that

The volume of the box is equal to

`V=LWH`

substitute the values and solve for H

`72=(3)(4)H`

`H=72/(12)=6\ in`
