A prism with rectangles as bases.
length
width
height
Surface Area= 2lw + 2wh + 2lh
Volume= length · width · height
3
A prism with triangle bases.
Surface Area= 2(1/2 base · height)* + (bottom)side +(front)side + (back)side
*Multiply by two because you have two triangles
Volume= 1/2 · base · height · length
4
A figure in space with three or more triangular faces and a base in the
shape of a polygon.
Base/Length
height
Surface Area= Length • Width + 4*(1/2 bh)
Width
*multiply by 4 because you have 4 triangular faces.
Volume=1/3 • L• W • H

Answer:
a=1/2(a+b)h
=1/2(12+15)•10
=1/2(27) •10
=1/2(270)
