Step-by-step explanation:
surface area = (2*0.5*12*8) + (2*10*10) + (12*10)
= 96 + 200 + 120
= 416 cm^2
Answer:
2640 cubes
Step-by-step explanation:
20 cm x 12 cm x 11 cm = 2640 cm^3
9 in the first box and 3 in the second :)
Answer:
<em>6x+72</em>
Step-by-step explanation:
Multiply 6 times x to get 6x. Then multiply 6 by 12 to get 72. Then put an addition sign to make another simplified equation. 6(x+12) is equal to 6x+72.
Answer:
The base is 90 sq
Step-by-step explanation:
Formula for Area= 1/2*b*h
where b is unknown and area = 54sq
<h2>Placing in formula</h2>
1/2 *b*12 = 54sq
12b = 54*2
12b /12 = 54*2/12
b = 9sq
