aria totala= aria laterala+2 aria bazei
aria totala=aria laterala+2 x 24
aria totala=aria laterala+48
volumul=aria bazei x inaltimea
168=24 x inaltimea
inaltimea=168:24
inaltimea=7
volumul= lungime x latime x inaltime
168=lungima x4x7
168=lungimea x28
lungimea= 168:28
lungimea=6
aria laterala=2 x(lungimea x inaltimea+latimea x inaltimea)
aria laterala=2x(6x7+4x7)
aria laterala=2x(42+28)
aria laterala=2x70
aria laterala=140
aria totala=aria laterala+2 aria bezei
aria totala=140+48
aria totala=188
eu am facut-o dupa formulele gasite pe net...

Abazei=24 cm²
latura 1=4 cm
latura 2 =24:4=6 cm
V=168 cm³
h=168:24=7 cm
Alaterala=(24+4)x2x7=392 cm²
Atotala=392+24x2=440 cm²
