Answer 2

Question :Find the volume of water in a rectangular aquarium of length 20 centimet

breadth 15 centimetres and height 12 centimetres if it is half full.

Answer

• length = 20cm
• Breadth = 15cm
• height = 12cm

If the tank is half filled then the:

• length will be 1/2 of 20cm
• breadth will be 1/2 of 15cm
• height will be 1/2 of 12cm

New length , breadth and height will be

• length = 10cm
• breadth = 7.5cm
• height = 6 cm

$volume = l \times b \times h \\ v = 10 \times 7.5 \times 6 \\ v = 60 \times 7.5 \\ v = 450.0 {cm}^{3}$

450 {cm}^{3} [/tex]
