Answer:
3). 900 bricks
4.) h=15 inches
Step-by-step explanation:
3). the total volume is 450x18x108=874,800
now divide that by the volume of each brick
874,800 divided by 972=900
4)The volume of box A =10x12x18=2160 so the volume of box B is half of that so it is 1080.
The volume of Box B is base area x height=volume so
72h=1080, divide 1080 by 72 and h=15
