Question

The volume V of a rectangular box in terms of its length l, width w, and height h is given by the formula V=lwh.


Part A

Choose the formula for the width of a rectangular box, in terms of its volume and other dimensions.

A. w=Vhl

B. w=hlV

C. w=Vlh

D. w=lVh

Part B

Find the width w of a box with volume V = 120 cm3, l = 3 cm and h = 5 cm.


width =

cm

Answer 1

Answer

Part  A

None of the expressions given is the answer. The answer is w=V/(l*h)

PART B

w=8cm

Step-by-step explanation:

Part A

From the formula given to calculate the volume, we have to isolate the with w:

$V=l*h*w\\V/(l*h)=w$

PART B

We know the formula to calculate with from Part A. Next, we replace given values in the formula.

w=V/(l*h)

w=120/(5*3)

w=120/15

w=8 cm
