Answer 1

Answer:

this is your answer step by step

Answer 2

Given :-

• Surface area of cuboid is 758cm² its length and breadth are 14cm and 11cm respectively

To find :-

• Height of cuboid

Solution :-

• Surface area of cuboid = 758 cm²

• Length of cuboid = 14 cm

• Breadth of cuboid = 11 cm

As we know that

→ Total surface area of cuboid = 2(lb + bh + lh)

Where " l " is length, " b " is breadth and " h " is height of cuboid.

Now, according to question

→ Total surface area of cuboid = 758cm²

→ 2(lb + bh + lh) = 758

→ (14*11 + 11*h + 14*h) = 758/2

→ (154 + 11h + 14h) = 379

→ 154 + 25h = 379

→ 25h = 379 - 154

→ 25h = 225

→ h = 225/25

→ h = 9 cm

Hence,

• Height of cuboid is 9 cm
