Question

Va rog dau coroana imi trebuie acum la scoala.
Succes!!

Answer 1

3.

L=528 m iar l = L:3=528:3 = 176 m

P = 2(L + l) = 2(528 + 176) = 1408m

A = L×l = 528×176 = 92928 m²

4.

Volum cub = a³ = 34³ = 39304 m³

aria bazei = a² = 34² = 1156 m²

5.

volum paralelipiped

l = 15 m

h = 20m

Volum = L × l × h dar L = l

3. l = 528:3 = 176 m

P = 2(528 + 176) = 1408 m

A = 528×176 = 92928 m²

4.

Volum cub= 34³ = 39304 m³

aria bazei =34² = 1156 m²

5  

Volum = l² × h = 15² × 20 = 4500 m³
