The equation below shows the total volume (V), in cubic units, of 4 identical boxes with each side equal to s units: V = 4s3 If s = 2.5 units, what is the value of V? (5 points) 25 cubic units 30 cubic units 62.50 cubic units 156.25 cubic unitsPlz help 

each side of a box is s = 2.5 units
volume of one box is length * breadth * height 
since its a cube all sides are equal 
volume of one box = s³ = 2.5³
since there are 4 boxes, 
total volume V = 4s³
V = 4 * 2.5³ = 4 * 15.625
                   = 62.50 cubic units
third response is correct
