Question

Узнай объем кроробки , если длина 12 см, ширина 7см,высота 4 см. Найди площадь боковых граней и дна данной коробки

Answer 1

V=a×b×c
где a=7см
b=12 см
c=4см
V=7×12×4=336 куб см-обьем
S=a×b
S=12×7=84кв см-площадь дна
S=4×12=48кв см-площадь боковых граней

Answer 2

Volume of the Box

To find the volume of the given box, we can use the formula: volume = length × width × height. Substituting the given values: volume = 12 cm × 7 cm × 4 cm.

Calculating the volume: volume = 336 cubic cm.

Surface Area of the Box

The surface area of the box can be calculated by finding the sum of the areas of all its six faces. The formula for the surface area of a rectangular box is: 2 × (length × width + width × height + height × length).

Substituting the given values: surface area = 2 × (12 cm × 7 cm + 7 cm × 4 cm + 4 cm × 12 cm).

Calculating the surface area: surface area = 2 × (84 cm² + 28 cm² + 48 cm²) = 2 × 160 cm² = 320 cm².

So, the volume of the given box is 336 cubic cm and the total surface area of its sides and bottom is 320 square cm.
