Because you can't build a solid figure with little squares. You need little cubes.

Since volume is the amount of space inside a object that is 3D you need to use cubic units also represented by the cubed exponent. This is because in square units your seeing how much space is in a square, or circle, or something that's 2D , you get it? Whatever the dimension is that's what the exponent of the unit will be, so like a volume of a cube is 125 m^3 because it's 3d.****

Volume is measured in cubic units because it represents the three-dimensional space an object occupies, calculated using the dimensions of length, width, and height. Square units are used for area calculations, which involve only two dimensions. Therefore, cubic units, like cubic meters (m³), are necessary for accurate volume measurements.

Jawaban:hitung resultan vektor tersebut menggunakan rumus yang ada di gambar. Diketahui: - Vektor A (Fx) = 12 N- Vektor B (Fy) = 10 N- Sudut antara vektor (θ) = 75°- √2 = 1,4- √3 = 1,7 Ditanya: - Resultan vektor (R) Penyelesaian: Rumus yang diberikan adalah: R = √(Fx² + Fy² + 2Fx * Fy * cos θ) 1. Hitung cos 75°:Kita tahu bahwa cos (A + B) = cos A cos B - sin A sin B. Kita bisa gunakan ini untuk mencari cos 75° = cos (45° + 30°):cos 75° = cos 45° cos 30° - sin 45° sin 30°cos 75° = (√2 / 2) * (√3 / 2) - (√2 / 2) * (1 / 2)cos 75° = (√6 - √2) / 4Kita tahu √2 = 1,4 dan √3 = 1,7, maka √6 = √(2*3) = √2 * √3 = 1,4 * 1,7 = 2,38cos 75° = (2,38 - 1,4) / 4 = 0,98 / 4 = 0,2452. Substitusikan nilai ke dalam rumus:R = √(12² + 10² + 2 * 12 * 10 * 0,245)R = √(144 + 100 + 58,8)R = √302,83. Hitung akar kuadrat:√302,8 ≈ 17,4 N Kesimpulan: Resultan vektor tersebut adalah sekitar 17,4 N.
