Atank holds 6.90 m3 of water. what is the volume in ft3? (3.28 ft = 1 m, remember significant figures, but this answer does not need units, since the answer must be in ft3)

Volume of tank = (given)

Since,

So,  

For :

The significant rule for multiplication, states that the number of significant figures in the answer obtained by multiplication is determined by the value with the lowest number of significant digits.
