The equation for density is:

To help you remember - my teacher told us to remember "We <span>♡ density," and the heart stands for </span>

, or

. Cheesy, but it works!<span>

Back to the problem:We know the mass if 49g and the volume is 7

, so plug these values into the equation for density:
Answer: The density is 7 g/
90ft by 7ft gives an area of:
