Question

The surface area of a cuboid is 4150 cm? If its length and breadth are 35 cm and 25 cm
respectively, find its height​

Answer 1

Answer:

area of cuboid = 2(lb+bh+hl)

4150 = 2(35×25 + h(b+l)

4150 = 2(35×25 + h(35+25)

4150= 2(35× 25 + h× 60)

4150= 875 + 60h

Find the value by dividing

Answer 2

GIVEN

SURFACE AREA OF CUBOID=4150CM

•LENGTH=35CM

•BREADTH=25

*FIND=HEIGHT OF CUBOID

•let

the height of be h

According to the question

$⟶2(lh + bl + hb) \\⟶ 2(35 \times h + 35 \times 25 + 25 \times h) = 4150 \\ ⟶2(35h + 875 + 25h) = 4150 \\ ⟶60h + 875 = 2075 \\ ⟶60h = 2075 - 875 \\ ⟶60h = 1200 \\ ⟶h = 20$

hence, the height of cuboid is 20cm
