Question

Find the surface area of this cuboid.

Answer 1

Answer :- total surface area of cuboid =2(LB+BH+HL)

Answer 2

SA of Cuboid = 2lb + 2bh + 2hl

Here B = Breadth

H = Height

L = Length

And values are

L = 3.5 m

B = 2 m

H = 2.5 m

Putting value

SA = 2(lb + hl + bh)

= 2(3.5×2 + 2.5×3.5 + 2×2.5)

= 2( 7 + 8.75 + 5)

= 2 × 20.75

= 41.5 m³
