My answer:
Given the information:
- The height: 4m
- The lenght: 13m
- The width 4m
The lateral area:
As we know, the lateral area can be calculated by the following formula:
= the perimeter of the base* the height
= (13 + 4 + 13 + 4)*4
= 136 m²
The surface area:
As we know, the lateral area can be calculated by the following formula:
= The lateral area + thhe base area + the top area
= 136 + 13*4 + 13*4
= 136 + 52 + 52
= 240 m2
