Linda is building steps for her porch. What is the volume of the steps? 144,000 cm3

288,000 cm3

324,000 cm3

540,000 cm3

Step-by-step explanation:

upper block:

length (l) = 120 cm

Width (w) = 30 cm

Height (h) = 60 cm

Volume of upper block = l * w * h

                                      = 120 * 30 *60

                                     = 216,000 cm³

Lower Block

l = 120 cm

w = 30 cm

h = 30 cm

Volume of lower block = 120 * 30 * 30

                                      = 108,000 cm³

Volume of steps = 216,000 + 108,000 = 324,000 cm³
