Question

Find the side of a cube whose surface area is 600 cms

Answer 1

$\huge{\underline{\mathfrak{\blue{Formula}}}}$

→ Surface area of cube = 6a² [ Here a denotes side of cube ]

Given that :-

Surface area of cube = 600 cm²

Now , we have to find out side of cube

→ 6a² = 600

→ a². = $\frac{600}{6}$

→ a². = 100

→ a² = 10²

→ a. = 10

So , the side of cube will be 10 cm

Verification :-

Surface area = 6a²

→ 6 × 10²

→ 6 × 100

→ 600 cm²

Hence verified .

Other formulae :-

Curved surface area of cube = 4a²

Volume of cube = a³

Diagonal of cube = a√3
