Question

If the volume of cuboid is 10000cm³. Height = 50m, Length = 20m, find the C.S.A of the cuboid.

Answer 1

Answer:

C.S.A of cuboid = 300m²

Given:

Height of cuboid = 50 m

Length of cuboid = 20 m

Volume of cuboid = 10000 m³

Step-by-step explanation:

⇒ To find the breadth of the cuboid

Let the breadth be "b"

• Volume of cuboid = l × b × h

According to Question,

Volume of cuboid = 10000 m³

⇒ l × b × h = 10000

→ 20 × 50 × b = 10000

→ 1000 × b = 10000

→ b = 10000/1000 = 10

∴ Breath of cuboid = 10 m

⇒ To find the C.S.A of the cuboid

• C.S.A of cuboid = 2h(l + b)

h = 50 m ... l = 20 m ... b = 10 m (as proved above)

→ 2h(l + b) ⇒ (2 × 50)(20 + 10)

→ 100 × 30

= 300

∴ C.S.A of cuboid = 300m²
