I believe the volume of the shape is 210mm. the formula is v=lwh. so you multiply all the numbers to get 210. hope that helped!
The square root of thirty lies between the numbers 5 and 6.
A googol is bigger than a billion.
Least 10 digit whole number = 1,111,111,111
It looks like the length of a and b should be the same. You can use the Pythagorean theorem (only works with right triangles):
a² + b² = c² (c is the hypotenuse or the longest side of the triangle, a and b are the other side lengths of the triangle)
a² + (4)² = (5)²
a² + 16 = 25
a² = 9
a = 3
a and b have a length of 3
