1.	A rectangular cuboid has a length of 6 cm , a breadth of 5 cm and a srface area of 104 square cm. Find the height of the rectangular cuboid.
Answer» Given :- A RECTANGULAR CUBOID has a length of 6 cm , a BREADTH of 5 cm and a surface area of 104 cm². To find :- Height of rectangular cuboid Solution :- As we know that → Total surface of cuboid = 2(lb + bh + lh) Where " l " is length, " b " is breadth and " h " is height. According to question → Total surface area of cuboid = 104 cm² → Length of cuboid = 6cm → Breadth of cuboid = 5cm Now, → Total surface area of cuboid = 104cm² → 2(lb + bh + lh) = 104 → 6 × 5 + 5h + 6H = 104/2 → 30 + 11h = 52 → 11h = 52 - 30 → 11h = 22 → h = 22/11 → h = 2 Hence, Height of cuboid is 2 cm

A rectangular cuboid has a length of 6 cm , a breadth of 5 cm and a srface area of 104 square cm. Find the height of the rectangular cuboid.

Answer»

A RECTANGULAR CUBOID has a length of 6 cm , a BREADTH of 5 cm and a surface area of 104 cm².

As we know that

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

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

→ Total surface area of cuboid = 104 cm²

→ Length of cuboid = 6cm

→ Breadth of cuboid = 5cm

Now,

→ Total surface area of cuboid = 104cm²

→ 2(lb + bh + lh) = 104

→ 6 × 5 + 5h + 6H = 104/2

→ 30 + 11h = 52

→ 11h = 52 - 30

→ 11h = 22

→ h = 22/11

→ h = 2

Hence,
