Answer:
please read explanation :)
1. 288 cm^3
2. 42
3. 30 cubic units
4. 18,000 cm^3
Step-by-step explanation:
Volume = l x w x h
1. Volume of original block = 480, volume of two pieces of wood sawed off = 3 x 4 x 8 = 96 times 2 pieces = 192 total
480 - 192 = 288 cm^3
2. first solve for volume of box = 3.5 dm * 5 dm * 2.5 dm = 35 cm * 50 cm * 25 cm = 43,750 cm^3 (because 1 dm = 10cm)
volume of 1 book = 2.5 cm * 24 cm * 17 cm = 1,020 cm^3
43,750 ÷ 1,020 = approximately 42.89, but you cannot put 0.89 book inside, so the answer is 42 books.
3. Volume of each cube = 1 cubic unit
Count how many cubes are in each layer
1st layer - 1
2nd layer - 4
3rd layer - 9
4th layer - 16
1 + 4 + 9 + 16 = 30 cubes * 1 cubic unit = 30 cubic units
4. The figure is made of two boxes. Volume of bigger box = 35 cm * 20 cm * 20 cm = 14,000 cm^3, volume of smaller box = 20 cm * 20 cm * 10 cm = 4,000 cm^3
14,000 + 4,000 = 18,000 cm^3
