A cuboid of dimensions 5 cm, 3 cm and 2 cm, then its surface area is -

${\blue{\underline{\underline{\pink{\textsf{\textbf{answer : }}}}}}}$

surface area of cuboid = 2lw+2lh+2hw

surface area of cuboid = 2×5×3 + 2×5×2 + 2×2×3

surface area of cuboid = 30+20+12 = 62cm^2

In this formula l stands for length, w stands for width and h stands for height.

Answer 2

Answer:

62 cm^3

Step-by-step explanation:

formula is 2lw+2hw+2hl

putting values: 2x3x2+2x5x2+2x3x5

= 12+20+30

therefore 62 cm cube
