Răspuns: [tex]\bf Aria~totala~_{soclu}= 28~cm^{2}[/tex]
Explicație pas cu pas:
(❁´◡`❁) Salutare!
[tex]\boxed{\boxed{\bf Aria~totala~a~ cubului = 6\cdot latura~cubului^{2}}}[/tex]
[tex]\bf At~_{cub~mare}= 6\cdot 2^{2} = 6\cdot4=24~cm^{2}[/tex]
[tex]\bf At~_{cub~mic}= 6\cdot 1^{2} = 6\cdot 1=6~cm^{2}[/tex]
[tex]\bf Aria~totala~_{soclu}= (6\cdot 2^{2} -1^{2})+ (6\cdot 1^{2}-1^{2})[/tex]
[tex]\bf Aria~totala~_{soclu}= (6\cdot 4 -1)+ (6\cdot 1-1)[/tex]
[tex]\bf Aria~totala~_{soclu}= 23+ 5[/tex]
[tex]\boxed{\bf Aria~totala~_{soclu}= 28~cm^{2}}[/tex]
P.S.: Am incercat sa iti exemplific problema prin doua zaruri ❤
