1 |
Problem |
The volume of the rectangular prism is 504 cubic cm, length, and height are 8 cm, and 9 cm, find its width. |
|
2 |
Step |
The given length, height and volume of rectangular prism are |
l = 8 cm |
3 |
Formula |
The volume of a rectangular prism is the product of length, width, and height |
\$v = l times w times h\$ |
4 |
Step |
Substitute the values of length, volume, and height in the formula, we get the width of a rectangular prism |
⇒ \$504 = 9 times w times 9\$ ⇒ 504 = 72w |
5 |
Step |
Move the w coefficient to the left-hand side ,simplify |
⇒ \$504/72\$ = w ⇒ 7 = w |
6 |
Step |
Therefore the width of a rectangular prism is 7 cm. |
