Answer 1

The surface area of the prism is
`1602\,\text{cm}^2`

Explanation:

Let the length be
`l=18\,\text{cm}`, the width be
`w=4.5\,\text{cm}`, and the height be
`h=32\,\text{cm}`:

`SA=2(lw+lh+wh)\\SA=2(18\cdot4.5+18\cdot32+4.5\cdot32)\\SA=2(81+576+144)\\SA=2(801)\\SA=1602\,\text{cm}^2`

Answer 2

1602cm²

Explanation:

2x18x32=1152

2x18x4.5=162

2x4.5x32=288

1152+162+288=1602
