Answer:

1,120 cm³

Step-by-step explanation:

Hello!

Think about it this way: There is a rectangular prism, with lengths of 20cm, 12cm, and 10cm, and another rectangular prism cut out of it with lengths, of 8cm, 8cm, and 20cm.

Larger rectangular prism

Volume = L * W * H

  • V = 20cm * 12cm * 10cm
  • V =  2,400cm³

Cut-Out Rectangular Prism

V = L * W * H

  • V = 8cm * 8cm * 20cm
  • V = 1,280cm³

Subtract:

  • 2,400cm³ - 1,280cm³
  • 1,120cm³

The total volume is 1,120cm³
