Answer: 1.) 180 cubic meters
2.) 302 square centimeters
3.) 16.33 centimeters
Step-by-step explanation:
1.) Volume of pyramid is bh/3
Base is 6×6 Height is 15/3
Multiply to get 180.
2.) Two sides are 5×11=55 each. Two sides are 6×11=66 each, and the two ends are each 5×6=30.
Add 55+66+30=151 then multiply 151×2=302.
3.) V=bh.
Triangular base is ab/2. Given a is 10 and base (edge of square side) is 12.
10×12/2= 60. Divide that into the given Volume: 1080cm^3
1080÷60= 16.33cm^2
