Question

total surface area of a cube is 600 metre square .find its edge​

Answer 1

Given:

T.S.A of a cube = 600 metre squared.

To Find:

The measure of it's edge.

Formula:

T.S.A of a cube = 6a^2

Explanation:

T.S.A of the cube = 600 metre squared

6a ^2 = 600 m^2

or, a^2 = 600/6 = 100

a = √100 = 10 cm

Answer:

The edge of the cube measures 10 cm.

Answer 2

Given:

• Total surface area of cube = 600 m²

To find:

• The measure of side of the cube.

Formula used:

• Total surface area of cube = 6a² sq.units

Solution:

Substituting the the given value in the formula:

→ 6a² = 600

→ a² = 600/6

→ a² = 100

→ a = √100 = 10 m.

Therefore, the side of the cube is 10 m.

Some formulas to know:-

• LSA of cube = 4a² sq.units
• Volume of cube = a³ cu.units
• TSA of cuboid = 2 × (lb + bh + lh) sq.units
• LSA of cuboid = 2 × (l + b) × h sq.units
• Volume of cuboid = lbh cu.units
