Question

Find the total surface area of the given cuboid.

• A. $130m^2$
• B. $131m^2$
• C. $132m^2$
• D. $133m^2$

Answer 1

Answer: (C)

$132m^2$

Given, length $\left(l\right)=8m$

breadth $\left(b\right)=5m$

height $\left(h\right)=2m$

Surface area of the cuboid $=2\times (lb+lh+bh)$

$=2\times (8\times 5+8\times 2+5\times 2)m^2$

$=2\times (40+16+10)m^2$

$=2\times 66m^2$

$=132m^2$

Hence, total surface area is $132m^2$
