Answer:
Well, to find the area of a:
square and rectangle you multiply (Length x Width) the formula is (LxW)
triangle you multiply (Base x Height) ÷ 2 the formula is (BxH/2)
The meaning of area is: the number of unit squares that can be contained in an object.
The meaning of volume is: the number of unit cubes that completely fill up a solid figure such as an ice cube.
To find the surface area of an object you:
Multiply the length times the width. (of only one side)
But for a triangle you multiply the base times the height, then divide the answer by 2 ( of only one side)
To find the volume you multiply the length times width times height.
But for a triangle you multiply the base times height.
