Find the surface area of this rectangular prism. Be sure to include the correct unit in your answer.

Surface area = 2(lb × bh × lh)

Length (l) = 9m

Breadth (b) = 4m

Height (h) = 5m

Substuting the values in the given formula

⇛Surface area = 2[(9)(4) × (4)(5) × (9)(5)]

⇛Surface area = = [(36) × (20) × (45)]

⇛Surface area = [720 × (45)]

⇛Surface area = 32400 m³

Hence , the surface area of rectangular prism is 32400 m³.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
