What is the formulas for Volume

Sagot :

Volume is measured in "cubic" units. The volume of a figure is the number of cubes required to fill it completely, like blocks in a box. Volume of a cube = side times side times side. Since each side of a square is the same, it can simply be the length of one side cubed. If a square has one side of 4 inches, the volume would be 4 inches times 4 inches times 4 inches, or 64 cubic inches. (Cubic inches can also be written in3.) Be sure to use the same units for all measurements. You cannot multiply feet times inches times yards, it doesn't make a perfectly cubed measurement. The volume of a rectangular prism is the length on the side times the width times the height. If the width is 4 inches, the length is 1 foot and the height is 3 feet, what is the volume?
CORRECT.... 4 inches is the same as 1/3 feet. Volume is 1/3 feet times 1 foot times 3 feet = 1 cubic foot (or 1 cu. ft., or 1 ft3).     
  I hope it could be helpful FOR U.

    

Cube = s³
rectangular prism/solid = lwh
Triangular prism/solid = bh (the area of the base, the triangle part, multiplied to the triangular solid's height)
Cylinder = πr²h
Sphere = (4/3)π
Cone
πr²(h/3)
Rectangular pyramid
lw÷ 3
