Question

A rectangular box has a volume of 15 cubic feet. The length, width, and height of the box are each doubled.

What is the new volume of the rectangular box?
A. 30 cubic feet
B. 60 cubic feet
C. 90 cubic feet
O D. 120 cubic feet

Answer 1

it should be D/120

Explanation:

An example of the box is:

5 the width

3 the length

1 the height.

That would be 5 x 3 x 1.

To double them, you must multiply each number by 2:

5 x 2 = 10

3 x 2 = 6

1 x 2 = 2.

Now the equation is 10 x 6 x 2.

First multiply 10 x 6 (60).

Then 60 x 2 (120).

120 is the answer
