1. Take 8cm as the axis and 6 as the base: volume =1/3 * 3.14 * 6 * 6 * 8 = 301.44.

Surface area = 3.14 * 6+3.14 * 6 * (6 * 6+8 * 8) *113.04+628 = 748.

2. Take 6 cm as the axis and 8 as the base: volume =1/3 * 3.14 * 8 * 8 * 6 = 401.92.

Surface area = 3.14 * 8 * 8+3.14 * 8 * (6 * 6+8 * 8) *1/3) = 200.96+837.25 =1038.

With 10 as the axis, the radius of the circle is 6 * 8 10 = 4.8, and the volume is1/3 * 3.14 * 4.8 *10 = 241.

Surface area = 3.14 * 4.8 * (4.8 * 4.8+3/7 *10 * 3/7 *10) *13)+3.
