Question

Начертите прямоугольный параллелепипед с длиной 5 см, шириной 4 см и высотой 1 см. Найдите площадь поверхности этого параллелепипеда и объем

Answer 1

1) 5·4=20(см²)-S поверхности прямоугольного параллелепипеда
2)5·4·1=20(см³)-∪

Answer 2

Начертить думаю сможешь.

V=abc=5*4*1=20(см)

P=2(a+b+c)=2*(5+4+1)=20(см)

Ответ:P=20 cm

V=20 cm

Answer 3

Drawing a Rectangular Parallelepiped

To draw a rectangular parallelepiped with a length of 5 cm, a width of 4 cm, and a height of 1 cm, you would start by drawing a rectangle with dimensions 5 cm by 4 cm. Then, you would extend lines perpendicular to the sides of the rectangle to represent the height of 1 cm. This would create a three-dimensional representation of a rectangular parallelepiped.

Calculating the Surface Area

The surface area of a rectangular parallelepiped can be calculated using the formula: Surface Area = 2lw + 2lh + 2wh where l, w, and h are the length, width, and height of the parallelepiped, respectively.

Substituting the given values: Surface Area = 2(5*4) + 2(5*1) + 2(4*1) Surface Area = 2(20) + 2(5) + 2(4) Surface Area = 40 + 10 + 8 Surface Area = 58 square centimeters

Calculating the Volume

The volume of a rectangular parallelepiped can be calculated using the formula: Volume = lwh where l, w, and h are the length, width, and height of the parallelepiped, respectively.

Substituting the given values: Volume = 5*4*1 Volume = 20 cubic centimeters

So, the surface area of the rectangular parallelepiped is 58 square centimeters and the volume is 20 cubic centimeters.
