How can the areas of certain shapes be found? what are the meanings of surface area and volume and how can surface area and volume be found

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.

Hope I helped ; )

i would say c is the best answer, hope it's right!

good luck! =)

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
