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
what is the earliest time when the pool will be empt ??
A)10 A.M.
B)11 A.M.
C) 4 P.M.
D) 5 P.M.
Answer: The value of the current is 1.91 A.
Step-by-step explanation:
From the question, the current I in an electrical conductor varies inversely as the resistance R of the conductor.
The equation can be written as,
Here, K is the proportionality constant and R is the resistance.
It is given in the problem that the current is 2 amperes when the resistance is 770 ohms.
Calculate the value of K by using above expression.
Put I= 2 A and R= 770 ohm.
Calculate the value of the resistance when R= 808 ohms.
Put K= 1540 and R= 808 ohms.
Therefore, the value of the current is 1.91 A.
