Amelia stores her gardening supplies in two cube-shaped-boxes. the smaller box has a volume of 100 in.^3. Amelia wants to know the total volume of both boxes.

s = length (in) of one side of the larger box.
Write an expression to show the total volume of the two boxes

Total volume = s^3 + 100

what is the total volume of both boxes if s equals 8 inches

Total volume = (8)^3 + 100

Total volume = 512 + 100
Total volume = 612 in^3

Therefore, the total volume of both boxes is 612 cubic inches.

2(3)^3+5

2(3)^3 + 5 = 2(27) + 5 = 54 + 5 = 59
