Question

Find the volumes of the following solids.
(1) A cube of side 1.4 mm
(2) A cuboid of dimensions
4.8 cm x 1.2 cm x 1.8cm. (3) a cylinder of base radius 12 cm and height 28 cm​

Answer 1

Answer:

1) 2.744 cm³

1) 2.744 cm³2) 9.072 cm³

1) 2.744 cm³2) 9.072 cm³3) 12,672 cm³

Step-by-step explanation:

1) Volume of Cube = (side)³ = (1.4)³ = 2.744 cm³

2) Volume of Cuboid = l × b × h = 4.8 × 1.2 × 1.8 = 9.072 cm³

3) Volume of Cylinder = πr²h = 22 ÷ 7 × (12)² × 28 = 12672 cm³
