Surface area=area needed to wrap a box
volume=amount of space in the box
surface area=2hl+2hw+2wl=2(hl+hw+wl)
volume=hlw
h=height
l=legnth
w=width
a. surface area is the outside area. lets say you have a cardboard cube and cut it on all the corners and edges so you ended up with 6 squares, the total areas of those squares is the surface area of the cube
volume is how much stuff can be put into the cube, we measure how many 1 by 1 by 1 cubes can fit into the object or how much water can fit in the cube
b. surface area is 2 dimentional since it is area and can be folded flat so the units would be square feet or square inches (ft^2, in^2)
volume is 3 dimentional since it is legnth width and height so it would be cubic foot, cubic inch (in^3, ft^3)
c. surface area=wrapping paper, wrapping stuff, painting an object
volume=how much water can fit in pool, how much punch to put in the jar to fill it up, which water bottle to bring so you have enough water
6000 x 10% x 5
=600x5
=3000
Answer:
I think the answer is: y = 0.5x^2 + 4x + 6, <3
Step-by-step explanation:
To answer the question, let x be the cost of a bedsheet and y that of a towel. The first purchase can be expressed as,
38x + 61y = $791.50
and the second as,
54x + 50y = $923
Solving for x and y simultaneously will give, x = $12 and y = $5.5. Thus, each bedsheet costs $12 and each towel cost $5.5.
