Answer 2

Sorry, no. There aren't any images, just the problem.

Answer 3

Rectangular based prism
Base shape: Rectangle, length 'L' and width 'W'
Area of base: L × W
Perimeter of base: 2(L+W)
Surface area = 2LW + 2(L+W)H


Circular based prism
Base shape: Circle, radius 'R'
Area of base: pR²
Perimeter of base: 2pR
Surface area = 2pR² + 2pRH




Triangular based prism
Base shape: Triangle: base 'b', height 'h', and sides S1, S2 and S3
Area of base: ½b×h
Perimeter of base: S1+ S2 + S3
Surface area = bh + (S1+ S2 + S3)H
