Answer: T.S.A = 4512cm^2
volume = 18900cm^3
weight = 17.01 kg
Step-by-step explanation:
T.S.A of cuboid = 2(lb+bh+lh)
= 2(42x25 + 25x18 + 42x18)
=2(1050 + 450 + 756)
=2 x 2256
= 4512cm^2
to find weight, we've to find the volume of the ice cube
therefore, volume of a cuboid = lbh
=42 x 25 x 28
=18900cm^3
weight of 1cm^3 of ice = 0.9grams
therefore weight of 18900cm^3 of ice = 18900 x 0.9
= 17010 grams = 17.01kg

Answer:
Step-by-step explanation:
we are given
Firstly, we will draw graph
We can see that from -4 to 0
we have two shapes
a rectangle and a quarter of circle
so, we can find areas and then we can combine them
now, we can simplify it
Then Miles carried the football 5 yards 8 times, that is 5x8
The correct answer is D. y = 5x8
You need to know the order of operations (PEMDAS)
Parentheses
Exponents
Multiplication AND Division
Addition AND Subtraction
So look at the equation. Are there exponents? No. Are there parentheses? No. What about multiplication and division? Yes, so you do these first.
3×6=18
So now you have 3-18+3
Now you have to do addition and subtraction (Left to Right)
3-18=-15
Now you have -15+3
-15+3=-12
-12 is your answer.
