What is the volume of a cube whose side is 10 m? (volume = length x width x height)
a.
0.001 m3
c.
100 m3
b.
10 m3
d.
1000 m3

Volume of the cube is 1000 m³.

Explanation:

It is given that,

Side of the cube, a = 10 m

We know that a cube have same length, breadth and height. The volume of the cube is given by :

i.e.

Here, l = b = h = 10 m

So,

So, the volume of the cube is 1000 cubic meters. Hence, this is the required solution.

So, the volume of the cube is 1000 cubic meters. Hence, this is the required solution.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
