Answer:
the answer b
Step-by-step explanation:
[surface area]=[area of 4 triangles sides]+[area of square base]
[area of square base]=24*24--------> 576 cm²
[area of one triangles side]
l=slant height
l²=16²+12²-------> l²=400-----------> l=20 cm
[area of one triangles side]=24*20/2--------> 240 cm²
[area of 4 triangles sides]=4*240----------> 960 cm²
[surface area]=[960]+[576]--------> 1536 cm²
Answer:
18 8/9 pots
Step-by-step explanation:
Total potting soil = 5 2/3 liters
Potting soil per pot = 3/10 liters
How many pots can Yao Xin fill?
Number of pots Yao Xin can fill = Total potting soil / Potting soil per pot
= 5 2/3 liters ÷ 3/10 liters
= 17/3 ÷ 3/10
= 17/3 × 10/3
= (17*10) / (3*3)
= 170/9
= 18 8/9
Number of pots Yao Xin can fill = 18 8/9 pots
