Question

the length breath and hight of a cuboid are in the ratio 6:5:3 if it surface are in 3150 cm find all it dimension and its volume​

Answer 1

Answer:

720 cm³

Step-by-step explanation:

otal surface Area of a Cuboid  = 2 (lb+bh+lh)  

Here Length L = 6x

Breadth B  = 5x

Height H = 3x

TSA =  2 ( 6x*5x + 5x*3x + 6x*3x) = 504 cm²

 2(63x²)  = 504

 x² =  504/2 *63

 x²  = 4     Therefore, x=2

Volume of the cuboid =  lbh  = 12*10*6  = 720cm³
