Question

the length breadth and height of a cuboid are in ratio 4 is to 3 is
to 2 and its total surface area is 5200 CM square find the dimension of the cuboid

Answer 1

Answer:

Let length of cuboid be4 x and breadth 3x and height 2x so surface area is 2 ( lb +bh+ hl)= 5200

Answer 2

Answer:

Let the length of the cuboid be 4X,breadth be 3X and height be 2X.

According to the question,

2(lb+bh+hl)=5200cm^2

2(4X×3X+3X×2X+2X×4X)=5200

2(12X^2+6X^2+8X^2)=5200

2×26X^2=5200

52X^2=5200

X^2=5200/52

X^2=100

X=10

Length=4X=40cm, breadth=3X=30cm and height=2X=20cm
