Answer & Step-by-step explanation:
For SURFACE AREA:
There are two triangles with base 8 and height 3
Area (triangles)= 1/2 (8)(3) × 2 (bc theres two) = 24
Theres two pieces to the "roof" with length , 2.8, and width 5.
Area(roof pieces)= (2.8)(5) × 2 = 28
Area(floor)= (8)(2.8)=22.4
Area(front&back)= (4.8)(8)×2=76.8
Area(2sides)=(4.8)(2.8)×2=26.88
Add up all the surface areas to find the total.
TOTAL SURFACE AREA= 24 + 28 + 22.4 + 76.8 + 26.88 = 178.08 square yards
FOR VOLUME:
This is two pieces the bottom box V=l×w×h and the roof part turned on its side V=B•h
V(box)= 8×2.8×4.8
=107.52
V(roof)=1/2(8)(3) × 2.8 = 33.6
Vol(total)=107.52+33.6= 141.12cubicyards
