12
Step-by-step explanation:
2x4=8
5x4=20
2x4=8
each side is multipled by 4
We need to find the surface area and volume for each rectangular prism. Here are the formulas I'm going to plug each prism's measurements.
S.Area=2(lw+wh+lh)
Volume: lwh
Question 75:
Volume: 3×1×3=9 cm³
Surface Area= 2(3)+2(3)+2(9)=6+6+18=30 cm²
Question 76:
Volume: 6×2×5=60 ft.³
Surface Area: 2(12)+2(10)+2(30)=24+20+60=104 ft²
Question 77:
Volume: 4×2×6=48 m³
Surface Area: 2(8)+2(12)+2(24)=16+24+48=88 m²
You have to subtract $40 from $68 make sure the larger number is in the front. If you did that all you would get $28.
Let H be the number hats and J the number of jackets. Then, we can write,
Now, since they want 250 items at least, we can write
Hence, the system of inequalities is
