Question

A box of facial tissue has a volume of 180 cubic inches. What is the width of the box if the height was 4 inches, and the length was 9 inches?

Answer 1

Solution :-

We have

`\begin{cases} \sf Volume = \frak{480 \: cu \: cm}\\ \sf Length = \frak{4 \: in} \\ \sf Height = \frak{4 \: in}\end{cases}`

Volume = lbh

180 = 9 × b × 4

180 = 36b

180/36 = b

5 = b

Therefore,

• Breadth is 5 in

Answer 2

The width of the box is 5 in

Explanation:

the formula for the volume of a rectangular box of length L, width W and height H is V = L*W*H. Here we know V, L and H and want to find W. Solving this equation for W, we get W = V/(LH).

With V = 180 in^3, H = 4 in and L = 9 in, W comes out to be

180 in^3

W = ------------------ = 5 in

(4 in)(9 in)

The width of the box is 5 in
