264 cm^2

Step-by-step explanation:

The solid is a rectangular prism. Every face is either a square or a rectangle.

The top face and bottom face are both squares with a 6 cm side.

The 4 vertical faces are rectangles 6 cm wide by 8 cm tall.

area = 2(6 cm * 6 cm) + 4(6 cm * 8 cm)

area = 2(36 cm^2) + 4(48 cm^2)

area = 72 cm^2 + 192 cm^2

area = 264 cm^2

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2
