Answer:
1560
Step-by-step explanation:
First (2 1/2)/(1/4) = (5/2)(4) = 20/2 = 10
Next, 3/(1/4) = 3(4) = 12
Lastly, (3 1/4)/(1/4) = (13/4) x 4 = 52/4 = 13
This means we need 10 rows of 12, 13 high. 10(12)(13) = 1560 cubes.
Another way is to multiply 2 1/2 x 3 x 3 1/4 = 5/2 x 3 x 13/4 = 195/8
A 1/4 inch cube is 1/4 x 1/4 x 1/4 for a volume of 1/64
(195/8)/(1/64) = (195/8)(64) = 1560 cubes.

Answer:
AB = 4/cos25
Put in calculator and put to the nearest hundredth or 2 dp
Step-by-step explanation:
The angle 25 is the starting point and adjacent is 4 and the unknown or we will call it x is the hypotenuse.
We will use CAH
Cos25 = 4/x
We need x by itself so
x = 4/cos25
Put in calculator and put to the nearest hundredth or 2 dp
