Hanah's BOB

For this BOB, im going to talk about surface area and volume of a triangular prism and cube.


Cube:
VOLUME
- To get the volume of a cube , you would have to do l x w x h , (length x width x height).

SURFACE AREA
- To get the surface area of a cube , you would need to draw a net. If all sides are labelled 4 cm , you would have to do , 2 x (l x w) + 2 x (h x l) + 2 x (w x h) = sa . You add them together and that'll e you answer.

Look at pictures .

Rectangular Prism:
VOLUME
- to get the volume of a rectangular prism , it's mostly the same as geting the volume for a cube. It has 6 sides , like a cube.

SURFACE AREA
- to get the surface area of a rectangular prism , it's alos mostly the same as getting the surface area of a cube.

Look at the pictures.
