- and a cylinder-rectangular prism
Triangular Prism:
b times h divided by 2
TSA: 36+36+45+50+40
TSA: 207 cm squared

Volume:
To find the volume of a triangular prism you use the formula Base times Height divided by 2 times the height.
for example 6cm times 3cm dived by 2 times 13cm.you would first times 6cm by 3 cm which is 18cm then divide 18cm by 2 which is 9cm
the you would go 18 times the height which is 13 and you would get the number

234 cm cubed
Volume of a cylinder?
The formula you would use is pie r squared
Volume of a rectangular prism? Formula length times the width times the height.
how to find out a volume with a fraction?
you would first find the volume by base times height divided by two times the height.
then when you get your final answer you would convert your fraction into a decimal and multiply your total answer by the decimal to get your final answer.
I am very much impressed by your post and I want to clear some of my doubts regarding the area of rectangle,so I am giving some of my views about it.Hope you will help me - The area of a rectangle is the product of its width and length.
