Calvin builds a form for a new cement step. The form he builds is 35 1/2in. Long, 20 in. Deep, and 6 in. High. How much cementis needed to fll the form?

231.78 lbs

Step-by-step explanation:

total amount of cementis needed = volume of form

volume of form in ft³ = length * depth * height

= 35.5/12 * 20/12 * 6/12

= 2.465ft³

density of cement = 94.01651 lb/ft³

mass of cement = density * volume

= 2.465 * 94.01651

= 231.78lb
