Srekar needs to increase the size of the prism below by 2 inches on each side. The original prism has a length of 3, a depth of 2, and a height of 1.

A prism has a length of 3, height of 1, and width of 2.

Which statements about the new prism are true? Check all that apply.
The new prism will have a length of 5 because 3 + 2 = 5.
The new prism will have a depth of 4 because 2 + 2 = 4.
The new prism will have a height of 2 because 1 times 2 = 2.
The volume will increase by 6 because 2 times 3 = 6 and each of the 3 dimensions is increased by 2.
Srekar could increase the volume by the same amount by just adding 6 to the height instead of 2 to each side.
The volume of the new prism will be 20 times 3 = 60 because there will be 20 cubes in each layer and the height will be 3 so there will be 3 layers of 20 cubes each. PLEASE ANSWER ASAP
