to find the volume and the surface area of
a rectangular prism.
What we did was draw a net of our shape out on gird paper and each cube represents 1 cm and then we labled it. Make sure the formula is writen down. The formula is ....
2 ( 4 x 2 )+ 2 ( 1 x 2 )+ 2 ( 4 x 1 ) =
To find the area of a rectangular prism you can use 2 diffrent stratigies or formulas. You can use...
( L x W ) x H = area or you can also use....... Area of the base x height. in this B.O.B we are going to solve it using both. First we drew a net of the rectangular prism.
Fromula : ( L x W ) x H = area
L = 8
W = 4 ( L x W ) x H
H = 1 ( 8 x 4 ) x 1 =
32 x 1 = 32 cm 3
The seccond way to solve this equation is to use the formula >>>>>> Area of the base x height = area of a rectangular prism.
The area of our base is 32 and 32 x our height would be 32 x 1= 32 cm 3. Since we are dealing with a 3 dimensional shape we have to make sure we use cubed witch is 3 instead of 2.
