Answer 6

To find the missing length of a rectangular prism, we first need to find the surface area formula for a rectangular prism:

Surface Area = 2lw + 2lh + 2wh

Given:
Height (h) = 9 cm
Width (w) = 9 cm
Surface Area = 432 cm²

Substitute the given values into the surface area formula:

432 = 2(9)(w) + 2(9)(9) + 2(w)(9)
432 = 18w + 162 + 18w
432 = 36w + 162
270 = 36w
w = 7.5 cm

Therefore, the missing length of the rectangular prism is 7.5 cm.

Answer 7

To find the surface area of a triangular prism, you need to add the areas of all the surfaces:

Surface Area = Area of Base + Perimeter of Base x Height + Perimeter of one base x Height

So the completed formula for the surface area of a triangular prism is:

Surface Area = Area of Base + Perimeter of Base x Height + Perimeter of one base x Height

or written as:

Surface Area (S.A.) = A + (S1 + S2 + S3)

where A represents the area of the triangular base and S1, S2, and S3 represent the areas of the three rectangular faces of the prism.
