A=bh - Area of parallelogram

A=1/2(b1 + b2)h - Area of trapezoid

A=3.14r2 - Area of circle

S=2B+Ph - Area of triangular prism Big B= area of a base

S=B+1/2Pl - Area of pyramid l= Slant height

V=Bh - Volume of prism, cylinder

V=1/3Bh - Volume of pyramid

V=4/33.14r3 - Volume of sphere

## Section 1

The

**base of a parallelogram**is the length of any one of its sides the perpendicular distance between the base and the opposite side is the**height of a parallelogram**.Area of a Parallelogram

## Section 2

The area of a circle is the product of pi and the square of the radius

A=pir2

## Section 3

A

**solid**is a three-dimensional figure that encloses a part of spaceA **polyhedron **is a solid that is enclosed by polygons

Faces, Edges, and Vertices of a Polyhedron

## Section 4

A

**net**is a two-dimensional pattern that forms a solid when it is folded. ## How to find surface area of a triangular prism S=2B+Ph S=2(1/2*4*3)+(5+5+4)15 S=300cm | ## How to find surface area of a cylinder S=2pir2 + 2pirh S=2pi(5)2 + 2pi(4)(10) S=425.99cm |

## Section 5

The

**slant height**of a regular pyramid of the height of a lateral face.Surface Area of a Pyramid

## Section 6

The

**volume**of a solid is a measure of the amount of space it occupies.The volume of a prism is the product of the area of the base.

## Finding volume of a rectangular prism V=Bh =lwh =10*2*3 = 320cm | ## Finding volume of a triangular prism V=Bh =1/2*8*7*13 =364 | ## Finding volume of a cylinder V=Bh =pi*r2*h =pi*42*15 =753.6cm |
