Answer:
we can use height 16m x 17m to get b/h 170+60+42=272m then divide by two to get SA= 136m^2 (you use 136m^2 x w/h of the rectangle base for volume to find m^3 answer.
Explanation:
To find the area of the triangular faces, use the formula A = 1/2bh, where A = area, b = base, and h = height. To find the volume To calculate the volume of a pyramid with a rectangular base, find the length and width of the base, then multiple those numbers together to determine the area of the base. Next, multiply the area of the base by the height of the pyramid. Take that result and divide it by 3 to calculate the pyramid's volume!
