The equation below shows the total volume (v), in cubic units, of 2 identical boxes with each side equal to s units:
v = 2s3
if s = 3.5 units, what is the value of v?
21.0 cubic units
24.5 cubic units
36.75 cubic units
85.75 cubic units

V = 2s3
s = 3.5
2 (3.5) 3 3.5×2=7.0
7.0×3 7.0×3=21.0 units or 21 units

21 units

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
