Answer:
45000 cm³
Step-by-step explanation:
Volume = length * breadth * height
Volume of stair 1 = 50 * 25 * 12 = 15000 cm³
Now second stair has an height of stair 1 + Stair 2
= 12 + 12 = 24 cm
Volume for second stair = 50 * 25 * 24 = 30000 cm³
Total volume of material used to make these two steps = 15000 + 30000 = 45000 cm³
