Question #1

At a daycare, Kiran sees children climbing on this foam play structure. Kiran is thinking about building a structure like this for his younger cousins to play on.

The entire structure is made out of soft foam so the children don’t hurt themselves. How much foam would Kiran need to build this play structure?

The entire structure is covered with vinyl so it is easy to wipe clean. How much vinyl would Kiran need to build this play structure?

The foam costs 0.8¢ per in3. Here is a table that lists the costs for different amounts of vinyl. What is the total cost for all the foam and vinyl needed to build this play structure?

When he examines the play structure more closely, Kiran realizes it is really two separate pieces that are next to each other.

How does this affect the amount of foam in the play structure?

How does this affect the amount of vinyl covering the play structure?
