Given the following information:
Katyanochek1 [597]
Step by Step Explanation

From the question,
the dimensions of the tank are;

L = 30 cm, way =0.075m and H = 15 cm

The density of water is given as
D = 1g {cm}^{ - 3}

The unit of density given in the question means that the mass of the water is in grams and the volume should also be in
{cm}^{3}

To find the volume of the water, we first convert the units of dimensions given in inches and metres to centimetres

1 inch = 2.54 cm

This implies that ,

H=15 inches=15×2.54cm=38.1cm

Also,

100cm=1m

This implies that,
w= \frac{0.075}{100 } = 7.5 \times {10}^{ - 4} cm

Now, the volume of water in the tank can hold, can be found from the relation;

V=L\times W\times H

This implies that,

v = 30cm \times (7.5 \times {10}^{ - 4} )cm \times 38.1cm

v = 0.857 {cm}^{3} \: to \: 3 \: d.p

Finally, we can calculate the mass of the water from the relation given;

D=\frac{M}{V}

This in implies that

1g {cm}^{ - 3} = \frac{m}{0.857 {cm}^{3} }
m = 1g {cm}^{ - 3} \times 0.857 {cm}^{3}
m = 0.857g


Hence the fish tank can hold 0.857g water.
