(e) Volume of a cube of edge 1 mm is ________.

Solution:

1 cu. mm

(f) If a box is filled with 8 cubes of edge 1 cm each its volume is ________.

Solution:

8 cu. mm

Question 2.

Find the volume of these cubes whose edges are given below:

(a) 4 cm

Solution:

4 cm

Volume of cube = Edge × Edge × Edge

= 4 cm × 4 cm × 4 cm

= 64 cu. cm

(b) 12 cm

Solution:

12 cm

Volume of cube = Edge × Edge × Edge

= 12 cm × 12 cm × 12 cm

= 1728 cu. cm

(c) 15 cm

Solution:

15 cm

Volume of cube = Edge × Edge × Edge

= 15 cm × 15 cm × 15 cm

= 3375 cu. cm

(d) 13 cm

Solution:

13 cm

Volume of cube = Edge × Edge × Edge

= 13 cm × 13 cm × 13 cm

= 2197 cu. cm

Question 3.

Find the volume of the following cuboids whose dimensions are given below:

(a) Length =15 cm, breadth = 8 cm, height = 5 cm.

Solution:

Volume of cuboid = length × breadth × height

= 15 cm × 8 cm × 5 cm

= 600 cu. cm

(b) Length = 5 cm, breadth = 3 cm, height = 2 cm.

Solution:

Volume of cuboid = length × breadth × height

= 5 cm × 3 cm × 2 cm

= 30 cu. cm

(c) Length = 10 cm, breadth = 5 cm, height = 3 cm.

Solution:

Volume of cuboid = length × breadth × height

= 10 cm × 5 cm × 3 cm

= 150 cu. cm.

(d) Length = 17 cm, breadth = 14 cm, height =12 cm.

Solution:

Volume of cuboid = length × breadth × height

= 17 cm × 14 cm × 12 cm

= 2856 cu. cm

Question 4.

An encyclopedia has a length of 30 cm, breadth 20 cm and height 8 cm. Find the volume of the encyclopedia.

Solution:

Length of encyclopedia = 30 cm

Breadth of encyclopedia = 20 cm

Height of encyclopedia = 8 cm

Volume of encyclopedia = 30 cm × 20 cm × 8 cm

= 4800 cu. cm

Question 5.

A dice has an edge of 4 cm. Find the volume of the dice.

Solution:

A dice has an cubic shape so we have to find the volume of a cube.

Volume of dice = Edge × Edge × Edge

= 4 cm × 4 cm × 4 cm

= 64 cu. cm

Question 6.

Find the volume of a brick of length 18 cm, breadth 9 cm and height 6 cm.

Solution:

Brick has a cuboidal shape, so we have find the volume of a cuboid.

Volume of brick = length × breadth × height

= 18 cm × 9 cm × 6 cm

= 972 cu. cm
