Monica found the volume of the prism below using the expression 4 + (4 times one-half). A prism has a length of 2 centimeters, height of 1 and two-thirds centimeters, and width of 2 centimeters. What errors did Monica make? Check all that apply. She should have counted only 2 unit cubes instead of 4. She should have counted 8 one-third cubes instead of only 4. She should have found the total value of the one-third cubes by multiplying by One-third instead of by One-half. Each fractional cube is worth Two-thirds instead of the One-half that she used. She cannot stack more than one layer of fractional cubes in a prism.
