Volume Calculator
Calculate the volume of common 3-D shapes.
Volume
24 cubic units
l × w × h
If units are cm → liters
0.024
If units are inches → gallons
0.1039
Prisms, and thirds of prisms
Any prism or cylinder is base area × height. Pointed solids — cones and pyramids — hold exactly one third of their enclosing prism, and a sphere is 4/3 π r³. Those few rules cover tanks, pools, boxes, and planters.
Volume to capacity
Cubic centimeters ÷ 1000 gives liters; cubic inches ÷ 231 gives US gallons; a cubic foot holds about 7.48 gallons. Compute in one length unit throughout, then convert once at the end.
