Surface Area of a Rectangular Prism is given by : 2 × { LB + BH + HL }
[tex]\heartsuit[/tex] L represents Length of the Rectangular Prism
[tex]\heartsuit[/tex] B represents Breadth of the Rectangular Prism
[tex]\heartsuit[/tex] H represents Length of the Rectangular Prism
Given : Length = 9 ft and Breadth = 5 ft and Height = 3 ft
⇒ Surface area of the given Prism = 2 × {(9)(5) + (5)(3) + (3)(9)} sq ft
⇒ Surface area of the given Prism = 2 × {(45 + 15 + 27} sq ft
⇒ Surface area of the given Prism = 2 × {87} sq ft
⇒ Surface area of the given Prism = 174 sq ft
