The lengths, breadths, and heights of two cuboids are in the ratio 2:3, 4:5 and 1:2, respectively. Find the ratio of their volumes​

Answer:

The lengths, breadths, and heights of two cuboids are in the ratio 2:3, 4:5 and 1:2, respectively. Find the ratio of their volumes

Thus the ratio of volumes would be: 6:25

Hope this helps. please mark me brain liest

Answer:

6:25

Step-by-step explanation:

Let's first find the volume of cuboid 1:

V = l*w*h

V1 = 1*3*4 = 12

Now let's find the volume of cuboid 2:

V2 = 2*5*5 = 50

V1:V2 = 12:50, which reduced down becomes 6:25.
