A cuboid is 30 cm long, 10 cm wide and 8 cm high. The sum of its edges is 1______ If you saw this cuboid into two cuboids, the surface area would increase at most______ , minimum increase______ ．

Sum of edge length: (30 + 10 + 8) × 4, = 48 × 4, = 192 (CM); maximum increase of surface area: 30 × 10 × 2 = 600 (cm 2); minimum increase of surface area: 10 × 8 × 2 = 160 (cm 2); answer: sum of edge length is 192 cm, maximum increase of surface area: 600 cm 2, minimum increase of surface area: 160 cm 2

In the cube abcd-a1b1c1d1 with edge length 2, e and F are the midpoint of dd1 and DB respectively, and the vertical plane ab1c of EF is calculated

I haven't seen this aspect for a long time. I don't know if you look at it. I remember that if a straight line is perpendicular to a plane, it will be perpendicular to the two intersecting lines in this plane. Then drawing a picture shows that the projection of EF on the abb1a1 plane is perpendicular to the straight line, and the projection of Ab1 in the ABCD plane is perpendicular to AC

As shown in the figure, in triangle ABC and triangle def, ab = De, BC = EF, am and DN are the middle lines on BC and EF respectively, and am = DN, indicating the reason for △ ABC ≌ Δ def

Because: ab = De, BC = EF, we know that the two sides are equal
Because am and DN are the midlines of BC and EF, BC = en and am = PN
So △ ABM ≌ △ pen so ∠ ABM = ∠ pen
So we can get △ ABC ≌ △ def through the edge (AB = de ∠ ABM = ∠ pen, BC = EF)

Have you ever read Andersen's fairy tales? What moved you most? Let's introduce them to you (except the little match girl)

His father is a shoemaker and his mother is a washerwoman. They work hard day and night to make ends meet. His family has only one small room and the furniture is very simple. But his father loves literature and art. There are paintings on the walls of the room and some porcelains and toys on the furniture, especially one with Xu

If you subtract 1 from the denominator of the fraction 25 / A and add 1 to the numerator, you can simplify it to 3 / 8. What is a

8
Idea: subtract 1 from the denominator and add 1 to the numerator,
That is, A-1 of 24 equals three of eight
So A-1 of 24 is 9 of 24
a-1=9
a=8
