If a cuboidal box has height, length and width as 20 cm, 15 cm and 10 cm respectively. Then its total surface area is:
Answers
Answer:
Step-by-step explanation:
height, h= 20 cm
length, l= 15 cm
width, b= 10 cm
total surface are, TSA= 2(lb+bh+hl)
= 2 x (150+200+300) cm^2
= 2 x 650 cm^2
= 1300 cm^2
Given - Dimensions of the cuboidal box
Find - Total Surface area
Solution - The total surface area of the cuboid is 1300 cm².
The total surface area of a cuboid can be calculated by the formula -
Total surface area = 2(length * breadth + breadth * height + height * length).
Keep the values in the formula to find the value of the total surface area of the cuboid.
Total surface area = 2(15*10 + 10*20 + 20*15)
Total surface area = 2(150 + 200 + 300)
Total surface area = 2(650)
Total surface area = 1300 cm².
Thus, the total surface area of the cuboid is 1300 cm².
