Answer 1

144 cm²

Explanation:

A prism's surface has 2 triangles & 3 rectangles.

In both the triangles , length of :

Perpendicular = 4 cm

Base = 6 cm

So , Area of both triangles =
`2((1)/(2) * Base * Perpendicular) = 2((1)/(2)* 6 * 4) = 24 cm^2`

In the 3 rectangles ,

Length = 8 cm

Width = 5 cm

So , Area of the rectangles =
`3( Length * Width) = 3(8 * 5) = 120 cm^2`

Hence the total surface area of the prism is = 120 + 24 =144 cm²
