How much space is inside the steps?
Answer:
The answer is 0.045
Step-by-step explanation:
1. Use this formula V=lwh
0.5 x 0.4 x 0.15 = 0.03
That is the volume of the lower prism
2. Do V=lwh again for the volume of the upper prism
0.5 x 0.15 x 0.2 = 0.015
3. After that add both of them up together
0.015 + 0.03 = 0.045

Answer:
W = 8.2 cm
Step-by-step explanation:
The perimeter formula is P = 2W + 2L and here the perimeter is 65.6 cm.
Thus, 65.6 cm = 2W + 2L. Substituting 3W for L, we get
65.6 cm = 2W + 2(3W) = 8W.
Solving for W by dividing both sides by 8, we get W = 65.6 cm / 8, or
W = 8.2 cm
