Find a surface area of the rectangular pyramid with these measurements length equals 15 mil with equals 12 mil high equals 10 mil express your answer as a decimal round to the nearest hundreds
To find the surface area of a rectangular pyramid, we need to calculate the area of each face and then sum them all up.
1) Base area: The base of the rectangular pyramid is a rectangle with length 15 mil and width 12 mil. The area of the base is given by: 15 mil * 12 mil = 180 square mil.
2) Lateral face 1 area: One of the lateral faces is also a rectangle with length 15 mil and width 10 mil (height of the pyramid). The area of this face is given by: 15 mil * 10 mil = 150 square mil.
3) Lateral face 2 area: The other lateral face has the same dimensions as the previous one, so its area is also 150 square mil.
4) Lateral face 3 area: The remaining lateral face is a triangle with base length 12 mil (width of the base) and height 10 mil. The area of this face is given by: (1/2) * 12 mil * 10 mil = 60 square mil.
Summing up all the face areas: 180 square mil + 150 square mil + 150 square mil + 60 square mil = 540 square mil.
Therefore, the surface area of the rectangular pyramid is 540 square mil.
