perimeter is going to be figured by using 2L + 2W 

2(60) +2W = 210
120 +2W = 210
-120           -120

2W = 90
divde by 2 on both sides

W = 45

Length of the shorter sides are 45 inches.

A rectangular prism has a volume of 540, if the length, width and height are all reduced 1/3 the size of the original. What is the new volume?

Answers

Answer:

20 units³

Step-by-step explanation:

Since all dimensions are being reduced by 1/3, that means that the total volume will decrease by 1/3 * 1/3 * 1/3 = 1/27 the size of its original.

That means that the new volume is 1/27 * 540 = 20 units³
