Answer 1

Answer to the given question☝.

Answer 2

Before, finding the answer. Let's find out on how we can find the answer.

• For the First question, we must use the formula of :

$\boxed{\sf Volume\ of\ cube={(edge)}^3}$

• For the Second question, we must use the formula of

$\boxed{ \sf Volume \: of \: Cuboid =l \times b \times h }$

$\rightarrow \bf \underline {Correct \: Question :}$

(1) Find the volume of these cubes whose edges are given :

(a) 4 cm

Volume of Cube = (edge)³

= (4)³

= 4 × 4 × 4

= 64 cm³

Hence, Volume of the Cube is 64 cm³

(b) 12 cm

Volume of Cube = (edge)³

= (12)³

= 12 × 12 × 12

= 1,728 cm³

Hence, the Volume of the Cube is 1,728 cm³

(c) 15 cm

Volume of Cube = (edge)³

= (15)³

= 15 × 15 × 15

= 3375 cm³

Hence, the Volume of the Cube is 3375 cm³.

--------------------------

(2) Find the volume of the following cuboids whose dimensions are given :

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

Volume of Cuboid = l × b × h

= 15 × 8 × 5

= 600 cm³

Hence, the Volume of Cuboid is 600 cm³

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

Volume of Cuboid = l × b × h

= 5 × 3 × 2

= 30 cm³

Hence, the Volume of Cuboid is 30 cm³

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

Volume of Cuboid = l × b × h

= 10 × 5 × 3

= 150 cm³

Hence, the Volume of Cuboid is 150 cm³

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

Volume of Cuboid = l × b × h

= 17 × 14 × 12

= 2856 cm³

Hence, the Volume of Cuboid is 2856 cm³.
