Volume of cube is side power 3
therfore cubic root volume = side length
volume = 512 --> cubic root 512 =8 cm
side length is 8 cm if it was doubled
side length= 16 cm
therefore side length after doubling =
side power 3
(16) to the power 3 = 4096 cm3
Answer:
Suppose that you had a right angle triangle. Note that if you take it and another copy of it (moved around a bit) the two triangles together can be placed to make a rectangle.
This rectangle has four 90 degree angles adding up to 360 degrees. Since the triangles are congruent each triangle has half as many degrees, namely 180. So this is true for any right triangle.
Suppose you triangle is not a right triangle. Draw a perpendicular from the vertex opposite the longest side, to the longest side. What you have now is two right triangles which, by the above contain 360 degrees in total. But if you look at the two right angles that add up to 180 degrees so the other angles, the angles of the original triangle, add up to 360 - 180 = 180 degrees.

Answer:
4.15 times larger
Step-by-step explanation:
8x108=864
2x104=208
864/208=4.15
2000 cm^2
Step-by-step explanation:
we simply round the dimensions of 50.8 cm to 50 cm and 40.6 cm to 40 cm, and we multiply 50*40 cm to get to 2000cm^2 (it is squared because this is area)
