Answer 1

Answer:

false hai cause

total surface area of a cube is 6L square

Answer 2

Answer:

True

Step-by-step explanation:

Cube is the type of cuboid having same length, height and breadth.

Total surface area of cuboid = 2 ( lb + bh + lh )

i.e. Total surface area of cube = 2 ( lb + bh + lh )

Let the side be s.

= 2(s(s) + s(s) +s(s))

= 2(3s²)

= 6s²

So both the formula for tsa of cube is right.

T.S.A. of cube = 2 ( lb + bh + lh ) or 6s²
