Which statement would give a correct method for finding the volume of the prism?
She knows there are 30 unit cubes in the bottom layer. Since the height is 4, there are 4 layers of 30 cubes each. She should
multiply 4x30 - 120. The volume is 120 cubic units.
She knows there are 11 cubes along the bottom and the height is 4, so she should multiply 4 x 11 -44. The volume is 44
cubic units.
She knows there are 30 unit cubes in the bottom layer. She will need 4 more layers, so she should add
30+30+30+30+30 - 150. The volume is 150 cubic units.
She knows there are 11 cubes along the bottom, and she needs 3 more layers. She has 33 cubes already in the prism, so
she should add 11+11+11+33 - 66. The volume is 66 cubic units.
