Answer:
Step-by-step explanation:
you have to find the area of each side
for the two triangles(front and back sides) A=BH/2 so 45 but since there are two triangles you multiple by 2 so 90
For two rectangular sides(the ones on the sides) A=LW so 144.2 but there are two so 288.4
For the bottom rectangle A=LW so 140
Then add them together
90+288.4+140= 518.4
