Where I live, the winters can get really cold. Temperatures can be 30 one day and then -1 the next. I wake up at 6 in the morning for school, and when I start getting ready for school, I am freezing! My bed and blanket are super warm, but as I get out and get dressed, my clothes are cold and I end up hiding in my bed to get warm. By unwritten family rules, my older sister always gets the quilt in the morning. I often just wear my winter coat instead, but it gets really uncomfortable to shuffle around in a big coat.

My question is, what can I do to stay warm? I always wear warm fuzzy socks to bed, but I don't have any super warm pakamas. Please help, I am so cold!

A closed box with a square base has to have a volume of 12,000 cubic inches.

Find a function for the surface area of the box.

A) f (x) = 2x^2 + (72,000 / x)

B) f (x) = 2x^2 + (48,000 / x)

C) f (x) = x^2 + (48,000 / x)

D) f (x) = 2x^2 + (12,000 / x)

Can anyone give me the correct answer and explain the steps?
I want to understand the concept fully for my exam next week.

Thank you in advance.

I have an outdoor shed that has a high pitched roof that will allow an upper floor to be added. The pitching starts at 10 feet. To lay a floor down, what size crossbars should I lay down left to right so that I can place plywood on top of this that will provide good stability for support. The floor will contain boxes and overflow items, but not heavy items such as machinary.

Are 2 X 4 beams heavy enough, and if so, how far apart should they be? I assume 3/4 inch plywood is acceptable as the floor on top of the plywood.

Thanks
