True or False
A geometric composite figure is a figure made up of many shapes.
TRUE
Area of a triangle
A = 1/2bh
32.5 units2
Volume of a cube with s = 11
1,331 units3
Surface Area of a cube with side 5
150 units2
Volume is written in units squared/square units
FALSE
It has 3 dimensions so it is written in units CUBED (to the power of 3)
Area of a circle
(3.14)r2
Area of a square with side 3.25
10.5625 units2
Volume of a rectangular prism with side lengths 2, 4, 8
64 units3
Surface Area of a rectangular prism with sides 3, 4, 5
94 units2
A cylinder is made up of 2 circles and a square in the center
FALSE
It is made up of a rectangle in the center
Surface Area of a Cylinder
2(3.14)r2 + h(2(3.14)r)
Area of a circle with radius of 4
50.24 units2
Volume of a triangular prism with a base of 5, height of 8 and depth of 10.
200 units3
When you account for surface area you must do what with the sides of a shape that touch or connect?
You must subtract the area of the sides that touch.
The volume formula for many shapes is V = Bh where B stands for the measure of the base shape
FALSE
B is the AREA OF THE BASE in a volume formula
s3
Area of a rectangle with L = 4 and W = 10
40 units2
Volume of a cylinder with radius of 10 and height of 6
1,884 units3
How many times do you subtract the area of the side that connects the two shapes in a composite figure?
TWICE (because you lose it from each shape)
Surface area, because it deals with 3-D figures, is written in cubed units.
FALSE
Area is always written in square units
Volume gets cubed units
Surface Area of a Rectangular Prism
SA = 2LW + 2LH + 2WH
Area of a circle with diameter of 12
113.04 units2
1,157.625 units3
Surface Area is found in units3 because they are 3 dimensional shapes
