Question

Find the total surface area of a cube whose dimension 7√3cm

Answer 1

Total surafce area of a cube = 6a²

so TSA = 6(7√3)²
= 6(49×3)
=6(147)
=882 cm²

Answer 2

SOLUTION.....


Total Surface Area of a Cube :-

$6 {a}^{2}$
where,
$a = 7 \sqrt{3} cm$
so,
$6 \times {(7 \sqrt{3} )}^{2}$
$882 {cm}^{2} .$
Therefore, area of cube will be 882cm^2.
