Here is a video on how to find the surface area of a rectangular prism:

Triangular Prism: base x height divided by 2 x height.
3x8.5/2 x 5
=12.75 x 5
=63.75m³

Rectangular Prism: lxwxh
=20x8x16
=2560cm³

Triangular Prism: base x height divided by 2 x height
=8 x 4/2 x .5
16 x 6.5= 104
3/8= 0.375
0.374 x 104 =39cm³

Circular Prism: pie r squared x height
d/2= radius
12/2= 6
=3.14 x 6 x 6 x 15
=1695.6cm³

Rectangular Prism

Net

l x w

T=5 x 10=50m

F=10 x 6 = 60m

S=6 x 5 =30m

TSA = 2(T+F+S)

= 2(50+60+30)

= 2(140)
