Calculate the surface area (in square units) of the shape represented by the nets shown below.
Rectangular Prism
Surface area = 80 square units
(4 x 4) x 2 = 32
(3 x 4) x 4 = 48
32 + 48 = 80
Rectangular Prism
Surface area = 62 square units
(5 x 3) x 2 = 30
(2 x 3) x 2 = 12
(5 x 2) x 2 = 20
30 + 12 + 20 = 62
Rectangular Prism
Surface area = 48 square units
(4 x 4) x 2 = 32
(1 x 4) x 4 = 16
32 + 16 = 48
Triangular Prism
Surface area = 51 square units
(2.5 x 5) x 2 = 25
(4 x 5) = 20
(4 x 1.5 ÷ 2) x 2 = 6
25 + 20 + 6 = 51
