​

Answer 1

Answer:

2(30+12+10)

2×52

104 cm²

Answer 2

Answer:

The T.S.A of Cuboid whose dimensions are 5cm, 6cm, 2cm js 104 sq. cm.

Step-by-step explanation:

• The total surface area of a cuboid is the sum of all its surfaces.
• The formula for the total surface area of a cuboid is given as, 2 (lb + bh + lh)

where l, b, and h indicate, length, breadth, and height of the cuboid.

Given: l = 5 cm, b = 6 cm and h = 2cm

Find :  T.S.A of Cuboid

Formula

T.S.A of Cuboid = 2 (lb + bh + lh)

=2 [ (5 × 6)+ (6 × 2)+ (5 × 2)]

=2 [ 30+ 12+ 10]

= 2[52]

= 104 sq. cm.
