Answer: 6300 cm 2

Step-by-step explanation: To find the volume of a 3d shape you have to use the formula L x W x H or (Length times Width Times Height).

So now we can see 15 x 15 x 28 = 6300

So you answer is 6300 cm 2

Btw if you did not know the 2 above cm means squared :)

Hope this helped have a nice day :)))))
