Question

Determine the surface area of a rectangular prism with the following dimensions:

Length = 5 cm, Width = 1 cm, Height = 8
a.

212 sq. cm

c.

120 sq.cm
b.

106 sq.cm

d.

290 sq. cm

Answer 1

b. 106 sq.cm

Explanation:

A=L×W

A1= 2(5×8) = 2(40) = 80

A2= 2(1×8) = 2(8) = 16

A3= 2(5×1) = 2(5) = 10

Total area = 80 + 16 +10 = 106 sq. cm
