I. 10× 10= 100 (square meter)

1.5×100 =150 (m3)

Answer: The building area is 100 m2, and the pool volume is 150 m3.

2.6×6=36 (square centimeter)

282.6÷36=7.85 cm

A: The height of this cylindrical machine part is 7.85 cm.

Three. 12.56÷3. 14=4 (m)

4÷2=2 (meter)

2×2×3. 14= 12.56 (m2)

12.56× 4.8 ÷ 3×1= 20.096 (m3)

0.2× 10=2 (m2)

20.096÷2= 10.048 (m)

V. 20÷2= 10 (cm)

10× 10×0.3=30 (cubic centimeter)

Solution: Let the height of conical iron block be x cm.

Judging from the meaning of the question, 3×3×x÷3=30.

9x÷3=30

3x=30

x= 10

Answer: The height of the tapered iron block is 10 cm.
