Answer:
Below
Explanation:
First find the area of the triangle
A = bh/2
= (5)(10)/2
= 50/2
= 25 in^2
*the height of the triangle is 10 because we are disregarding the 3 inches as it is not a part of the triangle
You can now find the volume of the triangular part
V = area x height
= (25)(10)
= 250 in^3
Now find the volume of the rectangular part
V = LWH
= (10)(5)(3)
= 150 in^3
Add these two up to get the total volume
150+250 =400 in^3
I hope that is correct.... good luck!
