To find the surface area of a rectangular prism, you can use the formula (SA = 2(lw + lh + wh)), where (l), (w), and (h) are the length, width, and height, respectively. For a prism with dimensions 3m (width), 4m (length), and 8m (height), the surface area calculation is (SA = 2(3 \times 4 + 3 \times 8 + 4 \times 8) = 2(12 + 24 + 32) = 2 \times 68 = 136 , \text{m}^2). Therefore, the surface area of the rectangular prism is 136 square meters.
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.
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

To find the possible whole number dimensions of a rectangular prism with a volume of 30m^3, we need to factorize 30 into pairs of whole numbers. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. By pairing these factors, we can determine the possible dimensions of the rectangular prism. The possible whole number dimensions for a rectangular prism with a volume of 30m^3 are: 1m x 1m x 30m, 1m x 2m x 15m, 1m x 3m x 10m, 1m x 5m x 6m, 2m x 3m x 5m.
