Determine the surface area of the rectangular prism below.
Length = 10cm
Width = 5cm
Height = 2cm
a) 80 cm²
b) 100 cm²
c) 160 cm²
d) 17 cm²
Answer:
c) 160 cm²
Explanation:
The formula for the Surface Area of a rectangular prism =
A=2(wl + hl + hw)
Length = 10cm
Width = 5cm
Height = 2cm
Hence:
Area =2× (5 × 10 + 2 × 10 + 2 × 5) cm²
= 2 × ( 50 + 20 + 10) cm²
= 2 × (80) cm²
= 160 cm²
