Square area perimeter total surface area and volume
Answers
Answer:
Let’s say you need a box to hold bags of marbles. The more bags you have to ship the bigger box you need. You need a lot of room inside the box. This room is called volume. It is 3-dimensional (width, length, and height. The unit could be cubic inches, cubic centimeters, or maybe liters.
Area measures surface. A piece of paper 8” x 10” would cover a surface area of 80 square inches. Area is 2-dimensional (width and length).
Perimeter is 1-dimensional (length). If you have to build a frame for a picture from wood molding, you need to add 2sides, a top, and a bottom. For an 8” x 10” picture you would add 8 + 10 + 8 + 10. The perimeter is 36”. It is common to miter the corners when you build a frame so you might add an extra foot for the corners.
Step-by-step explanation:
area = a²
perimeter = 4a
total surface area = 6a²
volume = a³
