how to solve the volume and surface area of rectangular prism:
the formula of finding the volume of rectangular prism :
V = lwh
example: find the volume of a rectangular prism with a 6 m long, 3 m wide and 8 m high.
substitute :
V = ( 6 m ) ( 3 m ) ( 8m )
V = 144 m³
the formula of finding the surface area of rectangular prism:
SA = 2 (lw + lh + wh )
"given the example lets get the surface area of the problem:
substitute:
L = 6m
W = 3m
H = 8m
SA = 2 ( (18m ) + ( 48m ) ( 24 m ) )
SA = 36m + 96m + 48m
SA = 180 m²
