$\mathbb{PROBLEM:}$

What is the surface area? 2 mm 3 mm 1 mm square millimeters.

$\mathbb{SOLUTION:}$

• $\sf{SA = 2mm \times3mm \times 1mm }$

• $\sf{SA = 2x(2 \times 3 + 2 \times 1 + 3 \times 1)}$

• $\sf{SA= 22 \: square \: millimeters^{2} }$

Answer 2

Answer :

Surface area is 22mm²

Required solution :

After noticing the question we got to knew that we need to calculate the surface area of cuboid and we've been provided with the values of length, breadth and height of it.

★ Surface area of cuboid :

• S.A. =2 (lb + lh + hb)

Substituting values,

>> S.A. = 2 (2 × 3 + 2 × 1 + 3 × 1)

>> S.A. = 2 (6 + 2 + 3)

>> S.A. = 2 (8 + 3)

>> S.A. = 2 (11)

>> S.A. = 2 × 11

>> S.A. = 22
