Answer 1

Answer:

2m, 125cm³

Step-by-step explanation:

(8)

Dimensions of a cuboidal tank:

Length = 6 m.

Breadth = 3.5 m.

Volume of cuboid = 42000 l.

We know that volume of cuboid = Length * Breadth * Height

⇒ 42000 litres = 6 * 3.5 * h

⇒ (42000/1000) m³ = 21 * h

⇒ 2 = h

Therefore, height of a cuboidal tank = 2 m.

(9)

We know that Total surface area of cube = (6a)².

⇒ 150 = 6a²

⇒ 25 = a²

⇒ a = 5.

Volume of a cuboid = (a)³

                                 = (5)³

                                 = 125 cm³.

Therefore, Volume of cuboid = 125 cm³.
