A rectangular prism with a length of 11m, width of 8m and height of 3m has a volume of 264m3
3m by 5m by 3m
2*(3*5 + 5*8 + 8*3) m2 = 2*(15 + 40 + 24) m2 = 2*79 m2 = 158 m2
Yes - as an example, a 4m by 3m by 2m prism has a volume of 4 x 3 x 2 = 24 m3, the same as a 24m by 1m by 1m prism. However, they have different surface areas. The 4m by 3m by 2m has surface area (4 x 3 x 2) + (4 x 2 x 2) + (3 x 2 x 2) = 24 + 16 + 12 = 52 m2. The 24m by 1m by 1m has surface area (24 x 1 x 2) + (24 x 1 x 2) + (1 x 1 x 2) = 48 + 48 + 2 = 98 m2.

Assuming this is a rectangular prism, the surface area would be 2LW+2LH+2HW. So the surface area for this object would be: 2*3*5+2*3*8+2*8*5=30+48+80=158 square meters.
use the net to find the lateral area of the prism 3m 6m 3m 6m 15m
2*(3*5 + 5*8 + 8*3) m2 = 2*(15 + 40 + 24) m2 = 2*79 m2 = 158 m2
240 m3 - without using a calculator !
2*(8*5 + 5*3 + 3*8) = 2*(40 + 15 + 24) = 2*79 = 158 m2
V = 8 * 4 * 3 = 48 m3 A = 2*(8*4 + 4*3 + 3*8) = 2*(32 + 12 + 24) = 2*68 = 136 m2
