Question

Did I do this right?


I have to find the lateral area of a right rectangular prism (diagram in the comments).

What I did was this;
A=2h(L+W)
A=2(3)(6+4)
A=6(10)
A=60

Answer 1

the lateral area is the area of the 4 sides (leave out the top and bottom)
the area of one side is Length*height. 3*6=18 is one side. the side opposite is the same, so 36 for the 2 long sides. the shorter side is 3*4=12. together with its opposite side 24.
add together: 36+24= 60

so your formula works.
