Answer:
D) 126 in²
Explanation:
A rectangular prism is 3 inches long, 5 inches wide, and has a height of 6 inches. What is its surface area?
The formula for the surface area of a rectangular prism =
A=2(wl+hl+hw)
Where
W= Width = 5in
H = Height = 6 in
l = Length = 3 in
Surface area =
2(5 × 3 + 6 × 3 + 5 × 6) square inches
2(15 + 18 + 30) square inches
2(63) square inches
= 126 square inches (in²)
Option D is correct
