To find the surface area of a solid, we need to add up the area of each face.
For a rectangular solid with dimensions 12, 16, and 10, the surface area would be:
- The area of the top and bottom faces: 2 x (12 x 16) = 384 square units
- The area of the front and back faces: 2 x (12 x 10) = 240 square units
- The area of the left and right faces: 2 x (16 x 10) = 320 square units
Adding these areas together, we get a total surface area of:
384 + 240 + 320 = 944 square units.
Therefore, the surface area of the solid with dimensions 12, 16, and 10 is 944 square units.
