yaa its simple u have to use formula and then u can solve easily
1. u have to fins the shape
2. in question its given 12,10,7.5
3. so u have to use cuboidal formula which is 2(lb+bh+hl)
4. u have to apply
5. 2(12*10+10*7.5+7.5*12)
6. 2(120+75+30)
7. 2(225)
8. 450mcube

Answer:
330 m²
Step-by-step explanation:
Here length of room ( L ) = 12 m
Breadth of room ( B ) = 10 m
Height of Room ( H ) = 7.5 m
We know that
Area of Four Walls = Lateral Surface Area of Cuboid = 2 ( L + B ) × H
= 2 ( 12 + 10) × 7.5
= 15 × 22
= 330 m²
volume its L*B*H
yea but in question they didn't ask for volume :)
