Estimate an answer to the question: How many sticky notes would it take to cover the cabinet, excluding the bottom?
Earlier, you learned about a cabinet being covered with sticky notes.[br][br]How could you find the actual number of sticky notes it will take to cover the cabinet, excluding the bottom? What information would you need to know?[br]
Use the information you have to find the number of sticky notes to cover the cabinet. Show your reasoning.
Here is a rectangular prism built from 12 cubes:[br][br][img width=164,height=220]https://lh4.googleusercontent.com/FmbuNpnfDjRJCJRmxT4ET4i7DdjDs_R-4cYpNUdOS7c7nZfgJFjykmMTb3-fGMeloRgYtC6emjW08da0ziBt2aq2bdxjTDLNlUhq4OKMar1m5gkQNng8nkqO35YIHzqib-MygUJq[/img][br][br]It has six [b]faces[/b], but you can only see three of them in the sketch. It has a [b]surface area[/b] of 32 square units.[br]The applet has 12 blocks, too. They are all in the same spot on the screen, like a hidden stack of blocks. You will always know where the stack is because it sits on a gray square. To use a block, drag the red point to move it. Click on the red points to change from left/right movement to up/down movement.[br][br][img width=426,height=273]https://lh6.googleusercontent.com/dXmKVZvz7XTQFMaPyquqsXd_lmav6M7chwcKGg6h7qIBQyGtlnLoUpVOUChCg597d4MCPgDAFxbP9KXxW-Ul_5vru82b2PEYUKtW21aR07VWxQK5HItjCPwsoGU9yk7O96mqBNES[/img]
