To solve the problem you must apply the corresponding formulas for calculate the area of each figure. Therefore, you have:

1-A cube where the length of each edge is 4 inches: 96 square inches
A=6a^2=96 inches^2
2- A triangular prism where the area of each base is about 20 square inches, the length of each side of the base is 6 inches, and the height of the prism is 2 inches:
76 square inches.
3- A square pyramid with a base length and slant height of 5 inches: 75
square inches.
A=2(5)(5)+5^2=75 inches^2
4- A rectangular prism with a length of 5 inches, a width of 4 inches, and a height of 3 inches:
94 square inches .
A=2(4x5+3x5+3x4)=94 inches^2
