GIVEN:

Edge of the cube = 23cm.

TO FIND:

Find the surface area of the cube?

SOLUTION:

Let the egde of the cube x

FORMULAE TO FIND:

$\boxed{ \sf \purple{Surface \: area \: of \: the \: cube = {6a}^{2} }}$

SOLVING BY APPLYING THE FORMULA:

Surface area = 6 ( 23 × 23 ) cm²

=> 6 × 529 cm²

=> 3174 cm²

KNOW MORE:

• Total surface area of a cube is 6a².
• Volume of a cuboid is l×b×h.
• 1cm² = 1ml.
• 1l = 1000cm³.
• 1m³ = 100000cm³ = 1000l = 1kl (kilolitre).
