Question

Find the total surface area of the following cuboids :
a. Length = 4m , Breadth = 2m , Height = 2m
b. Length = 8m , Breadth = 4m , Height = 2m​

Answer 1

TSA OF CUBOID = 2 ( lb+bh+lh )

For a. TSA = 2 ( 4×2 + 2×2 + 4×2 )

= 2 ( 8+4+8 )

= 2 × 20

= 40 m^2

For b. TSA = 2 ( 8×4 + 4×2 + 8×2 )

= 2 ( 32+8+16 )

= 2 × 56

= 112 m^2
