•Rectangular prism - Multiply the measurement of the length times the width, then times the height  

•Cube - Since all sides are the same measurement, it would be the measurement of any side, or edge, cubed, or a³  

•Prism - Find the area of the base, then multiply the area times the height of the prism. Area would be length times width (B), or B x h  

•Triangular prism - Find the area of the base (b), then multiply the area times the length (l) between the triangular bases. Area of the base would be ½ times the base times the height (h) of the triangle, or ½bhl  

•Cylinder - Find the area of the circular face using pi times the radius squared, then multiply that area times the height of the cylinder, so πr²h  

•Pyramid - Find the area of the base and multiply that area times the height of the pyramid and multiply by 1/3, or 1/3Bh  

•Square pyramid - Find the area of the base and multiply that area times the height of the pyramid and multiply by 1/3, or 1/3s²h  

•Rectangular pyramid - Find the area of the base and multiply that area times the height of the pyramid and multiply by 1/3, or 1/3 lwh  

•Sphere - For a sphere, multiply 4/3 times pi, then time the radius cubed, or 4/3 πr³
