Question

The length breath and height of a cubiod are the ratio 3:3:1 and its total surface area is 2200 find the denendions the cubiod ?

Answer 1

Answer:

Step-by-step explanation:

Let's take the common ratio as x

So, the ratio becomes as 3x,3x,1x

TSA of cuboid= 2200cm²

2(lb+bh+hl)= 2200cm²

2[(3x)(3x) + (3x)(1x) + (1x)(3x)]= 2200cm²

2[9x²+3x²+3x²]= 2200cm²

2[15x²]=2200cm²

30x²= 2200

x²= 2200/30

X= ✓73.3 (The value comes as 73.3bar)

X = 8.56cm

l = 3x= 25.68cm

b= 3x = 25.68cm

h= 1x= 8.56cm
