Arectangular prism has a base that is 5 cm by 7 cm and a height of 12 cm. if all dimensions are doubled, what happens to the volume? when the dimensions are doubled, the volume is twice the original volume. when the dimensions are doubled, the volume is three times the original volume. when the dimensions are doubled, the volume is four times the original volume. when the dimensions are doubled, the volume is eight times the original volume.

When the dimensions are doubled, the volume is eight times the original volume.

Step-by-step explanation:

The volume of a rectangular prism is given as =

Length is 7 cm

Width is 5 cm

Height is 12 cm

So, volume is = cubic cm.

Now we are given, that all dimensions are doubled. So, the new dimensions are :

Length becomes 14 cm

Width becomes 10 cm

Height becomes 24 cm

New volume becomes =   cubic cm.

Dividing 3360 by 420 to know, by how many times the volume differs.

times

So, the correct option is - When the dimensions are doubled, the volume is eight times the original volume.

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
