Answer:
Total surface area of cuboid = 174 meter²
Step-by-step explanation:
Given:
Length of cuboid = 9 meter
Width of cuboid = 5 meter
Height of cuboid = 3 meter
Find:
Total surface area of cuboid
Computation:
Total surface area of cuboid = 2[lb + bh + hl]
Total surface area of cuboid = 2[(9)(5) + (5)(3) + (3)(9)]
Total surface area of cuboid = 2[45 + 15 + 27]
Total surface area of cuboid = 2[87]
Total surface area of cuboid = 174 meter²
