Answer 2

Answer:

The answer to this is 60cm cubed

Step-by-step explanation:

So there are 3 faces that we know the area ( All different faces because their values are different.)

(+ they are adjacent which already helps, we could have done the question without this info tho)

I will be supposing what the areas are on the faces, but it doesnt matter since the result will be the same if you change the numbers 15 20 or 12 around the faces. Face 1 could be 12 or 15, face 2 could be 20 or 15 and face 3 could be 20 or 12 as well.

Face 1= 20

Face 2=12

Face 3=15

Since they are adjacent and we only know the area, we gotta find the height, base and length to find the volume.

face 1 is adjacent to face 2 so we find the highest common factor which will be 4

face 1 is adjacent to face 3 so the highest common factor is 5

face 2 is adjacent to face 3 so the highest common factor is 3.

Now, we dont know which one is the base height or length, but it doesnt matter, all we gotta do is multiply them together.

4*3*5=60

And there you go, the volume of the cuboid is 60cm cubed.

Hope this helped =D
