Need help please someone

Answer 1

Answer:

let's divide the figure into the two parts.

surface area of cuboid=2(lb+bh+hl)

surface area of cuboid=2(12×4+4×6+6×12)

surface area of cuboid = 288 unit²

diameter of cylinder =4

radius=4/2

surface area of half cylinder= pi×r(h+r)

surface area of half cylinder=3.14×2×(12+2)

surface area of half cylinder=87.92 unit²

surface area of figure=288 unit²+ 87.92 unit²

surface area of figure = 375.92 unit²
