Question

Monica found the volume of the prism below using the expression .

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 instead of by .


Each fractional cube is worth instead of the that she used.


She cannot stack more than one layer of fractional cubes in a prism.

Answer 1

b and c

Explanation:

i took the test <3

Answer 2

See Explanation

Explanation:

The expression and the dimension of the prism are not given.

So, I will just give a general expression.

The volume of a prism is:

`Volume = Length * Width * Height`

Assume that:

`Length = 2`

`Width = 2`

`Height = 1(2)/(3)`

See attachment

Monica's expression should be:

`Volume = 2 * 2 * 1(2)/(3)`

And the solution will be:

`Volume = 2 * 2 * (5)/(3)`

`Volume = (20)/(3)`
