(b) 2263 m^2

(c) 2200 m^2

(d) 4783 m^2

The question was posed to me by my school teacher while I was bunking the class.

My enquiry is from Surface Area and Volume of Different Solid Shapes in division Surface Area and Volumes of Mathematics – Class 10

Answer 1

Right option is (c) 2200 m^2

Best explanation: The lateral surface area of a cuboid = 2h(l + b)

= 2 × 22 (27 + 23)

= 2200 m^2
