Question

Which expression is not equal is NOT equal to the volume of the prism

A) 5+4+2
B) 5×(4×2)
C) (5×4)×2
D) 5×4+5×4​

Answer 1

A. To find the volume of this figure you need to multiply the length, width, and height. B and C are just two different ways of writing 5 x 4 x 2, and C means the same thing because PEMDAS would require you to do (5 x 4) + (5 x 4), or 2(5 x 4) because multiplication comes before addition.
