Question

6) A rectangular fish tank is 70.00 cm long, 300.00 mm wide, and 300.00 m deep.

Answer 1

Answer:

Volume of water it can hold 63000,000 cm³

Mass of water is 63000,000 g.

Explanation:

Given data:

Length of tank  = 70.00 cm

Width of tank = 300.00 mm

Height of tank = 300.00 m

Volume of water it can hold  = ?

Mass of water = ?

Solution:

First of all we will convert the units into same unit.

Width of tank = 300.00 mm × 1 cm / 10 mm = 30 cm

Height of tank = 300.00 m× 100 cm / 1 m = 30000 cm

Volume of water it can hold:

V = l×w×h

V = 70.00 cm × 30 cm × 30000 cm

V = 63000,000 cm³

Mass of water:

Density of water from literature = 1 g/cm³

d = m/v

1 g/cm³ = m/ 63000,000 cm³

m = 63000,000 g
