Question

the surface area of a cuboid 758 cm ² . its length and breadth is 14 cm and 11 cm respectively find its height​

Answer 1

Answer:

b'total surface area(T.S.A)=758

length(l)=14

breadth=11

let height=x

So,

T.S.A.=2(lb+bh+hl)

Thus height of a cuboid is 9cm

Answer 2

Answer:

h= 9cm

Step-by-step explanation:

GIVEN,

Surface area = 758 cm²

length = 14cm

breadth = 11cm

NOW,

Surface area of cuboid = 2(lb×bh×hl)

758 = 2(14×11×11×h×h×14)

758÷2=154×11h×14h

379-154=25h

225=25h

225÷25=h

9=h
