Question

find the total surface area of the cuboid of length 8m'breadth 5m, and height 3m​

Answer 1

Answer :

• Total surface area of cuboid is 158cm²

Given :

• Length = 8m
• Breadth = 5m
• Height = 3m

To find :

• Total surface area of the cuboid

Solution :

As we know that,

• Totao surface area of cuboid = 2(lb + bh + lh)

where , l is length, b is breadth and h is height

》2(lb + bh + lh)

》2((8)(5) + (5)(3) + (8)(3))

》2(40 + 15 + 24)

》2(79)

》158 cm²

Hence, Total surface area of cuboid is 158cm²

More Explanation :

• Cuboid has 6 faces
• Cuboid has 12 edges
• Cuboid has 8 vertices
• Lateral surface area of cuboid = 2h(l + b)
• Volume of cuboid = lbh
• Total surface area of cuboid = 2(lb + bh + lh)
• where, l is length, b is breadth and h is height

Answer 2

_______________

♧Question♧

• find the total surface area of the cuboid of length 8m'breadth 5m, and height 3m.

♧Answer♧

Given data:-

• ➠Length = 8m
• ➠Breathe = 5m
• ➠Height = 3m

To find:-

• ➠Surface area of cuboid = ?

Solution:-

☆By using this formula

2lw+2lh+2hw

• ➠Put values in the formula
• ➠2(8)(5) + 2(8)(3) + 2(3)(5)
• ➠80 + 48 + 30
• ➠128 + 30
• ➠158m² Ans

Additional information:-

• Surface area of cuboid
• ➠2lw+2lh+2hw
• Volume of cuboid
• ➠l × b × h
