what is the solution of rectangular prism ?


Sagot :

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
