Answer:He will need 15 wax cubes.Step-by-step explanation:Hi, to answer this question, first, we have to calculate the volume of the pyramid:

Volume of the pyramid (P) = 1/3 x base area x height

Base area = side ²= 6^2 = 36 cm2

P = 1 /3 x 36 x 10 = 120 cm3

Next, the volume of each cube:

Volume of each cube (C) =side x side x side

C = 2 x 2 x 2 = 8 cm2

Finally we have to divide the volume of the pyramid (120) by the volume of each cube (8)

120 / 8 = 15

He will need 15 wax cubes.
