so i had a whole good answer written out and then the browser stopped responding :(
basically its 108 because you do the area normally for L x H, W x H and L x W
and then because there are two of each side with that area you times them by two
so 18 x 2 +
24 x 2
12 x 2
=36 + 48 + 24
= 108
but you may want to check my calculations again
sorry it's a bit rushed but I hope it makes sense and helps :)
A rectangular prism with a length of 11m, width of 8m and height of 3m has a volume of 264m3
1043.6
To determine the surface area of a rectangular prism, the two sides, adjacent sides, and ends of the prism must be added up. To do this, the sides are the product of the prism's length and height, the adjacent sides the width and height, and the ends the product of the length and width.
The area does not provide sufficient information to determine the length, width and height.
