Question

Find the volume of a
(i) Cuboid 5 cm by 4 cm
by 3 cm. (ii) Cube with edge V8 cm.​

Answer 1

Answer:

(1) volume of cubiod - lbh

-5*4*3=60 cm

the volume of cubiod is 60 cm.

Answer 2

Answer :-

• Volume of Cuboid = 60 cubic cm.
• Volume of Cube = 512 cubic cm.

Explanation :-

(i)

Volume of Cuboid :- l × b × h.

➞ Volume = 5 × 4 × 3.

➞ Volume = 20 × 3.

➞ Volume = 60 cubic cm.

(ii)

Volume of Cube :- (side)³

➞ Volume = (8)³

➞ Volume = 8 × 8 × 8.

➞ Volume = 64 × 8.

➞ Volume = 512 cubic cm.

Some Formulae to learn :-

• T.S.A. of Cuboid = 2(lb + bh + hl).

• L.S.A. of Cuboid = 2(l + b)h.

• T.S.A. of Cube = 6(side)²

• L.S.A. of Cube = 4(side)²

• Volume of Cube = (side)³

• Volume of Cuboid = l × b × h.
