The Surface Area of a Prism Formula is given as,
Surface Area Of A Rectangular Prism is A = 2 (wl + lh + hw)
Surface Area Of A Triangular Prism is A = bh + L (s1 + s2 + s3)
a – apothem length of the prism.
b – base length of the prism.
l – base width of the rectangular prism.
h – height of the prism.
Surface Area of a Prism Problems
Some solved problems on the surface area of a prism are given below :
a = 7 cm
b = 10 cm
h = 18 cm
Surface area of a triangular prism
= ab + 3bh
= (7 cm $\times$ 10 cm) + (3 $\times$ 10 cm $\times$ 18 cm)
= 70 cm2 + 540 cm2
= 610 cm2
a = 12 cm
b = 15 cm
h = 21 cm
Surface area of a pentagonal prism
= 5ab + 5bh
= (5 $\times$ 12 cm $\times$ 15 cm) + (5 $\times$ 15 cm $\times$ 21 cm)
= 900 cm2 + 1575 cm2
= 2475 cm2
