Your answer is 2 because 11 times 2 is 22
2387 divided by 2 days (which is 48 hours)
2387/48 = 49.7 is what I got.
The diagonal of a cube is the square root of 3x^2, where x is a side length....The three dimensional diagonal is the counterpart to the two dimensional hypotenuse found in a right triangle...mathematically a three dimension diagonal can be found with an extension of the Pythagorean Theorem adapted to three dimensions...
d^2=x^2+y^2+z^2 but since we are dealing with a cube, x=y=z=s where s is a side lenght...
d^2=3s^2 and we are told that the diagonal is 30 in. so
3s^2=30^2
3s^2=900
s^2=300
s=√300
s=10√3 in. exact
s≈17.3 in. (to the nearest tenth of an inch)
convert both dimensions to feet
1 mile = 5280 feet so 1/2 mile = 5280/2 = 2640 ft
1 yard = 3 ft so 600 yards = 600*3 = 1800 feet
now calculate area = 2640*1800 = 4752000 square feet
acres = square feet / 43560 so 475200/43560 = 109.09 acres
