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.

a mantle plume is an upwelling of abnormally hot rock within the earth's mantle. as the heads of mantle plumes can partly melt when they reach shallow depths, they are thought to be the cause of volcanic centers known as hotspots and probably also to have caused flood basalts.
