 Question 66897: Please help. I'm having trouble with this problem. The volume of a cube is given by V = s3, where s is the length of a side. Find the length of a side of a cube if the Volume is 1000 cm3. Answer: Click here to see answer by venugopalramana(3286)

 Question 66895: Please help.I can't solve this problem. A right triangle is a triangle with one angle measuring 90°. In a right triangle, the sides are related by Pythagorean Theorem,cˆ 2=aˆ2+bˆ2, where c is the hypotenuse (the side opposite the 90° angle). Find the hypotenuse when the other 2 sides’ measurements are 6 feet and 8 feet. Answer: Show work in this space . Click here to see answer by venugopalramana(3286)
