What is the surface area of the rectangular prism? lenth; 10 width;9 height;3(1 point)
The surface area of a rectangular prism can be calculated using the formula: 2lw + 2lh + 2wh.
In this case, the length (l) is 10, the width (w) is 9, and the height (h) is 3.
Plugging these values into the formula, we get:
2(10)(9) + 2(10)(3) + 2(9)(3)
= 180 + 60 + 54
= 294
Therefore, the surface area of the rectangular prism is 294 square units.
