Ответ:
1. Suprafața laterală este de 480 cm²
2. Înălțimea paralelipipedului este de 4,8 cm
3. Volumul paralelepipedului este de 648 cm³
Step-by-step explanation:
Un paralelipiped dreptunghiular are dimensiunea bazei de 15 cm, iar celălalt este 35 din primul. Suprafața totală măsoară 750 cm2. Din zona laterală; Înălțimea paralelipipedului; Volumul. Calcol
Aici avem
Dimensiunile bazei sunt;
a = 15 cm
b = 3/5 × 15 = 9 cm
c = Obligatoriu
De asemenea suprafața totală = 750 cm²
∴ deoarece suprafața totală = 2 · a · b + 2 · b · c + 2 · a · c
2 × 15 × 9 + 2 × 35 × c + 2 × 15 × c = 750
270 + 70 · c + 30 · c = 750
100 · c = 480
c = 4,8 cm
Suprafața laterală reprezintă suprafața totală mai puțin zona de sus și de jos
Prin urmare;
1. Suprafața laterală = 750 - 2 × 15 × 9 = 480 cm²
2. Înălțimea paralelipipedului = c = 4,8 cm
3. Volumul paralelipipedului = aria bazei × înălțimea
∴ Volumul paralelipipedului = 15 × 9 × 4,8 = 648 cm³.
