Answer:
252m^2
Step-by-step explanation:
The formula for surface area of a rectangular prism is 2(hl)+2(hw)+2(wl).
we just plug in the values.
2(12 x 6) + 2(12 x 3) + 2(6 x 3)
= 2(72) + 2(36) + 2(18) then simplify
= 144 + 72 + 36
= 252
Answer:
1420 bricks
Step-by-step explanation:
10 rows x 142 bricks in each row = 1420 bricks
1.
1 km = 1000 m
619.5 km = 619.5 * 1000 m = 619,500 m
2.
1,000 mm = 1 m
5,941 mm = 5.941 m
3.
2
4.
4
To solve for this, let's try the highest number x and y can be.
X < 5, so it can be 4.
Y < 6, so it can be 5.
4 + 5 = 9.
9 < 11, so x + y < 11.
Your missing inequality symbol is:
<
