Question

Calculate the surface area of a cuboid if the length breadth and height are 2cm 3cm and 1 cm respectively

Answer 1

surface area of cuboid= 2(lb + bh + hl)

SA = 2(2 × 3 + 3×1 + 1×2)

SA= 22 CM ²

Answer 2

QUESTION

Calculate the surface area of a cuboid if the length breadth and height are 2cm 3cm and 1 cm respectively.

SOLUTION

Here

• lengh (l) = 2cm
• Height (h) = 1cm
• breadth (b) =3cm

$\bf \large \: surface \: area \: of \: cuboid \: = 2(lb + bl + lh)$

$\bf \large = 2(2 \times 3 + 3 \times 1 + 1 \times 2) \\ = 2(6 + 3 + 2) \\ = 2(11) \\ \bf= 22 \: {cm}^{2}$
