Question 189705
Imagine a square 1 ft on each side and 3.8 grubs inside that square.
Then find the area of her lawn.
{{{60.4*80.2 = 4844.1}}} ft2
Each of the 1 ft x 1 ft squares in her lawn has 3.8 grubs, so
{{{3.8*4844.1 = 18407.5}}} grubs in her lawn
In terms of dimensions, it's
(grubs/ft2)(ft2/lawn) = grubs/lawn
