121, 31/3, 88, 6.5, 9, -10.5
sorry i can’t find a way to put the square root symbols!!
So, to find the volume of just the cement part, you need to find the volume of the whole shape, then find the volume of the garden. then subtract them to find the volume of just the cement sidewalk.
volume of garden: 16 x 6 x 1 (l x w x h)= 96 ft3
volume of whole: length=16+4+4=24, width=6+4+4=14, height=1
you have to add 4 to each sides of the length and width to get the entire length.
volume of whole=24 x 14 x 1=336 ft3
now subt.
336-90=246 ft3 would be the volume of the cement walkway.
The square root of 141 =

This is because the two factors are 3 and 47, which both aren't perfect squares. You cannot take anything out.
If you want it simplified (like with a calculator) it would be:
