Question - Calculating Surface Area and Volume

To find the surface area (SA) of a rectangular prism:

SA = 2(lw + lh + wh)

Where l = 80 cm, w = 40 cm, h = 55 cm:

SA = 2(80 \times 40 + 80 \times 55 + 40 \times 55)

SA = 2(3200 + 4400 + 2200) = 2(9800) = 19600 \, \text{cm}^2

For the volume (V):

V = l \times w \times h

V = 80 \times 40 \times 55

V = 176000 \, \text{cm}^3
