Question

Can u plz find surface area Don't get it so can u plz show your work thank you

Answer 1

Think of finding each surface area as finding the area of a 2D object

Lets start with the triangle.

area of right triangle = ab/2

6*8=48  48/2= 24

so the triangles surface area is 24, remeber there are 2 identical triangles so multiply 24 by 2 and get 48 again

now lets do one of the rectangles

area of rectangle is ab

so 4*10=40

lets add that to the total

48+40 = 88

Now lets do 8*4= 32

add to total again, 88+32= 120

and now do the last rectangle, 6*4=24

Now get the grand total of it all, 120+24 = 144

Thats how you do it :)
