using length x width x height, I believe it would be 10cm if the dimensions are in that order
A rectangular prism that measures 8.2cm 5cm and 2cm has a volume of 82cm3
2cm*5cm*3cm=30cm3The volume of the cuboid: 2*5*3 = 30 cubic cm
I am not sure what the point is for you to give us the dimensions of a rectangle and then ask what one of those dimensions is. Perhaps you are not sure whether the shorter or the longer of the two dimensions would be considered the length, and which the width. I would say that a rectangle measuring 2cm x 5cm is 2cm wide and 5cm long.
The volume is answered in cubic centimeters, which is typed out like this 1cm*5cm*6cm = 30 cm3
Mean = sum(X)/n = 15cm/5 = 3cm
Basic mental arithmetic... 2 x 5 x 8 = 80cm3.
The volume of the cylinder is: 15.7 cm3
5cm x 2cm x 6cm = 60 cubic cm.
