You can calculate the radius first, using the formula:area = 4 x pi x radius^2
Then you can calculate the volume from that.
25 yards2 ????If so....,Area sphere = 4*pi*r2You have area, so....,25 yrd2 = 4*pi*r2r = sqrt(25/4*pi)= 1.41 yards in radius-----------------------------Volume sphere = 4/3*pi*r3Volume = 4/3*pi(1.41 yrd)3= 12 cubic yards===============
A cube with this volume has a total surface area of 150 cm2. Each of its six sides comprises an area of 25 cm2
Well, darling, to find the volume of a cube, you simply cube the length of one side. Since the surface area of a cube is 6 times the side length squared, you can solve for the side length by taking the square root of 150/6. Once you have the side length, just cube it to find the volume. Easy peasy lemon squeezy!
Your problem is quite easy...Since getting the volume of a cube is s3 we will do the opposite of it will get its cube root* First get the cube root of 25 = 2.9 (I just round it off but the exact measure is 2.924017738) * Then use the formula 6s2 for solving the surface area SA = (6)(2.9)2= (6)(8.41)SA = 50.46
A 25 cm cube has all edges with a length of 25 cm. Therefore each face has an area of 25*25 = 625 sq cm. As a cube has 6 faces, the total surface area of the cube is 625*6 = 3750 square centimeters.
