The height of this pyramid will be:
√(26^2 - (48/2)^2) = 10cm
So the volume is: V = 1/3 * 48^2 * 10 = 7680 cm^3
Use the estimate but that should be more than the exact price
519.99(.0825) = 42.899
519.99 + 42.899 = $562.89
1. X/Y = Z
if x = 6, y = 2, then z = 3, not even
if x = 6, y = 3, then z = 2, even
<span>2. Z=XY </span>
so (z)^2 = 2*k (because x*y*z = 2k, where k is an integer)
<span>Sufficient, as if square of an integer is even ,then the integer is even</span>
