Answer:
8820 cm^3
Step-by-step explanation:
Volume of one prism = A(base prism)*height(prism)
A(base prism)= A(triangle) = 1/2*(base triangle)*Height(triangle)= 1/2*10*7 = 35 cm^2
Volume of one prism(or one candle) = A(base prism)*height(prism)= 35*6=210 cm^3
Volume of 42 candles = 210*42= 8820 cm^3
