Calculate the surface area (in square units) of the shape represented by the nets shown below.

Rectangular Prism

2d net corresponding to a cube

Surface area = 80 square units

(4 x 4) x 2 = 32

(3 x 4) x 4 = 48

32 + 48 = 80

Rectangular Prism

2d net corresponding to a cube

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

2d net corresponding to a cube

Surface area = 48 square units

(4 x 4) x 2 = 32

(1 x 4) x 4 = 16

32 + 16 = 48

Triangular Prism

2d net corresponding to a cube

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
