A fish tank is in the shape of a cuboid. The length of the fish tank is 0.8 m and the width is 0.3 m.
The volume of water in the fish tank is 108 litres.
1m cubed=1000 litres.
Work out the depth of the water in the fish tank.

Length = 0.8m

Breadth = 0.3m

Volume = 108litres = 108÷1000 = 0.108m³

Volume = l x b x h

0.108 = 0.8 x 0.3 x h

0.108 ÷ ( 0.8 x 0.3 ) = h

0.45 = h

step-by-step explanation:

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
