Question

The total
total surface area of a Cubaids fe
120m² if the length and breath of the cubaids are equal and the height is 2m find the length aSnd breath



​

Answer 1

Answer:

is it cuboid or cube

length and breadth so it's cuboid

Answer 2

Heyyy mate

here is your answer..

given, s.a of cuboid= 120m^²

2(lb+BH+lh) = 120m^²

let length and breadth= X m

so, according to question

2 ( x^2+2x+2x)= 120

x^2+4x= 120/2=60m^²

x^²+4x-60=0

x^²+(10-6)x-60

x^²+10x-6x-60

X(X+10)-6(X+10)

(X+10) (x-6)

X+10=0

X= -10

x-6= 0

X= 6

so length and breadth= 6m

hope it help yo
