Question

9.What is total surface area of cuboid, with sides 5,4,3.​

Answer 1

$\huge{\mathbb{\underbrace{\orange{SOLUTION}}}}$

The Total surface area of a cuboid (TSA) is equal to the sum of the areas of it's 6 rectangular faces, which is given by: Total Surface Area of a Cuboid (TSA) = 2 (lw + wh + lh) square units.

Sides of a cuboid = 5,4,3

Total surface area = 2(lw+wh+lh)

= 2[(5x4)+(4x3)+(3x5)]

= 2(20+12+15)

= 40+24+30

= 94
