-8 = y
Gear B will turn in Direction 1
<h2>135 cubic feet of concrete are required to create the platform.</h2>
Step-by-step explanation:
The dimension of lower step is 6 ft× 3 ft× 1.5 ft
and the dimension of upper step is 6 ft ×(9-3)ft × (1.5+1.5)ft = 6 ft × 6 ft ×3 ft
Therefore concrete are required to make lower step = (6×3×1.5) cubic feet
= 27 cubic feet
and concrete are required to make upper step = (6×6×3) cubic feet
=108 cubic feet
<h3>∴(108+27) cubic feet =
135 cubic feet of concrete are required.</h3>
