Answer:
B
Step-by-step explanation:
Answer:
Surface area:


Volume :

Neither:



Step-by-step explanation:
Surface area of the cuboid:
The Surface area of the cuboid = 2(lb) +2(bh) +2(hl)
Where
l =length of the cuboid
b = Breadth of the cuboid
h = height of the cuboid
So ,
The surface area will be
SA = 
SA = 
SA =
SA = 
SA = 432
Volumes of the cuboid:

Volume = 
volume = 576
Answer:
B
Step-by-step explanation:
It's a right triangle, so the pythagorean theorem will be used a lot.
First, find the side length on the left.
25^2 = 7^2 + y
y = 24
Now, knowing that 7 - 3 = 4 (the smaller side length), I can use this theorem again to find x.
4^2 + 24^2 = x^2
x = 
Just need to simplify it a little farther...
592 / 16 = 37, so B must be the answer.
15 miles per hour is the answer because 2/1/2 divided by 1/6 is 15
UPWARD JOURNEY
(g is -ive)
u= 80.5m/s
Height reached= u^2/2g= 324m
Height of the ball at topmost point of journey= 414m
DOWNWARD JOURNEY
(g is +ive)
u=0
We need to find the velocity at 89m from ground, which is equivalent to finding velocity at 325 m from the topmost point in downward direction.
v= √2gh= √2*10*325= 80.6= 81 m/sec(Answer)
