Volume: the amount of space occupied by an object is called volume.
The volume of a rectangular prism can be found by the formula:
VOLUME = LENGTH x WIDTH x HEIGHT
HEIGHT= 35 cm(3)
LENGTH= 13 cm(3)
WIDTH= 44 cm(3)
All you need to do multiply 35 cm² x 13 cm² x 44 cm²= The Volume.
V= 20020 cm²(3)
ANOTHER WAY TO FIND VOLUME:
To find volume you can use the formula:
BASE X HEIGHT
The base of the prism is a triangle, so we need to find the area of the triangle.
Area of the triangle = 1/2 x 8 x 4 = 16 cm(3)
The height of the prism is 12 cm(3).
Volume of the prism = A x H = 16 x 12 = 192cm(3)
THE SURFACE AREA:
How to find the surface area?
Every net conatins a top, bottom, front, back, and a right, and left side.
H= 30 cm(3)
L= 20 cm(3)
W=10 cm (3)
What is the surface area?
Top & Bottom= 2 (lxw)
Front & Back=2 (hxl)
Right Side & Left Side= 2 (hxw)
To get the measurments for each part of the net you need to follow steps above in brackets and multiply your answer by 2.
Top & Bottom=400cm(3)
Front & Back=1200cm(3)
Right Side & Left Side=600cm(3)
Now add all of your answers together to get the surface area:
400 cm(3) + 1200 cm(3) + 600 cm(3) = 2200 cm(3)
