Question

Find the surface area of the rectangular prism : $=1m^2$

• A. $180m^2$
• B. $202m^2$
• C. $313m^2$
• D. $188m^2$

Answer 1

The correct option is D $188m^2$

Surface area of rectangle is 2 x (Length x width + Length x height + Width x height)

Here, length $=7$ m, height $=6$ m and width $=4$ m

Therefore, the surface area of rectangle is:

$A=2\left(\right(7\times 4)+(7\times 6)+(4\times 6\left)\right)=2(28+42+24)=2\times 94=188$ m${}^2$

Hence, the surface area of the rectangular prism is $188$ m${}^2$.
