Question

The length and breadth and height of a cuboid are ratio 6 ratio 5 ratio 3 if it's total surface area is 504 cm square find its dimensions also find the volume of the cuboid

Answer 1

Answer:

answer is 12 cm2 is the answer

Answer 2

L=6a, B=5a, H=3a

Surface Area=2(b*l + l*h + b*h)

504cm2 = 2(5*6 + 3*6 + 5*3)------> 504=126 a^2 ---------->504/126=a^2

4=a^2---------> 2=a

L=12cm, B=10cm, H=6cm

V=l*b*h----------> V=12cm * 10 cm * 6 cm-------> V = 720 cm^3
