Answer:
5 cm
Step-by-step explanation:
The volume (V) of a cuboid is calculated as
V = lbh ( l is length, b is breadth and h is height )
Here l = 20, h = 12, V = 1200 and b is to be found, thus
20 × b × 12 = 1200, that is
240b = 1200 ( divide both sides by 240 )
b = 5
Product of 8 and the sum of 4 and a number:
sum of 4 and a number: (4 + n)
Product of 8
8 x (4 + n) is 112
8 x (4 + n) = 112
Distribute
32 + 8n = 112
Subtratc
8n = 80
Divide by 8
n = 10
The number is 10, and next time please put options because it says "Which equation could be used to solve for the number?" Thanks! :)
