Answer:
Step-by-step explanation:
area of front face=(12+8)/2 ×8=80 cm²
volume=80×22=1760 cm³
84 - 12 = 72, because the total age is 84, and we know that Michael is 12 years older than Lynn, making Lynn 72 years old.

Answer: 1,162.9 cm3
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a square pyramid: 1/3 x base area x height
Where
base area = base side length ^2
Replacing with the value given:
Base area = 15.9^2
base area : 252.81 cm2
Back with the volume formula:
V = 1/3 x base area x height
Replacing with the values given and solving for V (volume)
V = 1/3 x 252.81 x 13.8 = 1,162.9 cubic centimeters
