20 what is the volume of a box with the following dimensions: a height of 4m.
a width of 3m, and a length of 5m? b) what are the dimensions of a box
with twice the volume? c) what are the dimensions of a box with three
times the volume? d) what are the dimensions of a box with half the
volume?

Volume: 60 m^2

B.) 8 x 3 x 5

C.) 12 x 3 x 5

D.) 2 x 3 x 5

Step-by-step explanation:

A.) Volume is found by l*w*h:  4 x 3 x 5 = 60

For any dimension change problem, we can just change one value, typically we just do height.

B.) We're going to double the height, which has a value of 4

4 x 2 = 8

So we do 8 x 3 x 5 which is 120, double the original volume.

C.) We're going to triple the height

4 x 3 = 12

12 x 3 x 15 = 180

Triple the original volume

D.) We're going to divide the height into two

4/2 = 2

2 x 3 x 5 = 30

Half of the original volume.
