Answer 1

Answer:

28cm

Step-by-step explanation:

Since the two cuboids have the same volume, we use the volume of cuboid one to find the length of side y,

Volume of a cuboid = $length * breadth * height$

Volume of the cuboid with all sides given is = 7 * 4 * 2 = 56cm cubed.

Now we use that volume to calculate the length y,

56 = 1 * 2 * y

56 = 2y

y = 56/2

y = 28cm

Answer 2

Answer:

28 cm

Step-by-step explanation:

volume of a rectangle: l*w*h

the first cuboid: 7*4*2= 56

56=2*1*y

56=2y

28=y
