1. A cuboid goldfish tank without a cover is 0.6 meters long, 0.3 meters wide, 0.5 meters high and 0.4 meters deep. How many square meters of glass does it take to make the tank? How many liters of water does it take to fill the tank? 2. If a cuboid increases its height by 5 cm, it becomes a cube, and its surface area increases by 180 square cm, How many cubic meters of concrete should be used to cast such a concrete column? If an advertisement is pasted on the surface of the column, what is the maximum utilization area of the advertisement?

1. Base area 0.6 * 0.3 = 0.18, tetrahedral 0.6 * 0.5 = 0.30.3 * 0.5 = 0.15, at least 0.18 + 0.3 * 2 + 0.15 * 2 = 1.08, and 0.6 * 0.3 * (0.5-0.4) = 0.018l 2. Increase the surface of the cuboid to 180 △ 5 = 36, the length of the bottom edge to 6, the original height to 1, and the original cuboid volume to 6 * 1 = 36 cubic centimeters

Huanhuan said to Lele, "I'm eight years older than you. Two years later, my age is three times your age."______ I'm 40 years old

Suppose the age of Lele this year is x years old. From the meaning of the title, we can get: (x + 2) × 3 = x + 8 + 2, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 3x + 6 = x + 10, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 2x = 4, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp

Xiao Ming's report card is damaged in the middle. Can you find a way to work out the math and English scores
The average score was 82, including 89 for thinking, 69 for Chinese, 6 for English and 81 for nature

82x5-89-69-81-70-6=95
So 75 in math and 96 in English
