What is the name of the figure created by the net?
Triangular Prism
How many faces does the figure have? How many of those faces are bases?
6 faces total
2 bases
The cube has a side length of 3cm.
Find the surface area of the cube.
One Face:
A=(3)(3)=9cm^2
Surface Area:
9*6 faces= 54cm^2
Find the Volume of the figure:
V=4.5*11*3
V=4.5*33
V=148.5ft^3
What is Surface Area?
The area of all the flat surfaces on a 3D figure.
Name the following figure and draw its net:
Square Pyramid
How many edges and how many vertices does the figure have?
9 edges
6 vertices
Each face of the pyramid has the same base and height.
Find the Surface Area.
1 triangular face:
A=1/2(6)(10)
A=1/2(60)=30cm^2
4 faces:
30*4=120cm^2
Find Volume
V=10*3*6 1/2
V=30*6 1/2
V=195cm^3
What is Volume?
The amount of cubic units inside a 3D solid figure.
Draw a net for the figure, label the base and height for each face.
How many faces, bases, edges, and vertices?
5 total faces
1 base
8 edges
5 vertices
Find the total Surface Area of the figure.
Square Base: 4 x 4 = 16
Triangle Face:
A=1/2(4)(7)
A=14
Base+ 4 Triangle Faces
16+56=72ft^2
Use the formula to find the Volume of the figure.
V=5 1/4*3*3
V=5 1/4*9
V=21/4*9/1
V=189/4
V=47 1/4cm^3
What is the difference between Surface Area and Volume?
Surface Area: 2D, flat space, area of faces added together
Volume: 3D, solid space, V=lengthxwidthxheight
