Find the surface area of the prisim

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.

Step-by-step 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!

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
