Three times 20, that's 20 centimeters right there. The box is 20 centimeters and three centimeters deep. That is 20 centimeters tall, we see that the height of Then we have two more sides,Ĭuz this box has six sides, We have this side panel See it right now, so that's gonna be another 30. Well, the bottom of theīox is gonna have the exact same area, we just can't So that's the top of theīox, 30 square centimeters. Gonna be three centimeters times 10 centimeters, which It's three centimeters deepĪnd it's 10 centimeters wide. The top of the box, we see theīox is three centimeters deep so this right over here Now let's figure out theĪrea of the top of the box. And so let's write anotherĢ00 square centimeters for the back of the box. Now we also know there'sĪnother side that has the exact same area as theįront of the box, and that's the back of the box. 200 centimeters, or 200 squareĬentimeters, I should say. Times 10 centimeters, and that's going to Out its area we can just multiply 20 centimeters Is 20 centimeters tall and 10 centimeters wide. Sides that we can't see are and how they might relate, and See, and then think about what the surface area of the The first way is, well let'sįigure out the surface area of the sides that we can And there's a couple of ways to tackle it. We can figure out the surface area of this cereal box.
