Trapezoidal 6110

Calculate the volume of a 1.3 dm high pyramid with a trapezoidal base, the bases are 2.3 dm and 1.6 dm long, and its height is 1.8 dm.

Correct answer:

V =  1.521 dm3

Step-by-step explanation:

h=1.3 dm a=2.3 dm c=1.6 dm h2=1.8 dm  S=h2 (a+c)/2=1.8 (2.3+1.6)/2=100351=3.51 dm2 V=S h/3=3.51 1.3/3=1.521 dm3
