Question

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 1

Answer:

X is your answer so your answer is 2

Step-by-step explanation:

104=2(6*5+6*x +5*x)

104/2= 30+6x+5x

52=30+11x

52-32=11x

22=11x

22/11=X

X=2

Answer 2

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
