Answer 1

hii mate

=========

here is ur answer ^↓^

==============

→→to find area of the triangular prism

→area of 2 triangles
2(√3/4 a² ) { equilateral ∆ }
2(√3/4 × 6²)
2{√3/4(36)}
2(√3 ×8)
2(8√3)
16√3

→area of 3 rectangles

3(lb)
3(8×6)
3(48)
144

→⭐⭐area covered by fig is sum of area of 2 ∆s and 3 rectangles.⭐⭐

16√3+144
4(4√3+36)
4×4(√3+9)
16(√3+9)cm²✔✔✔

Answer 2

The surface area of this shape is 139.78 cm square.
A=ah+bh+ch+1/2✓-a^4+2(ab)^2+2(ac)^2-b^4+2(bc)^2-c^4.
=8•5.2+6•5.2+6•5.2+1/2✓-8^4+2(8•6)^2+2(8•6)^2-6^4+2(6•6)^2-6^4
=139.77709
or ≈139.78 cm square.
