Answer:

2bricks

Step-by-step explanation:

volume of cuboid = length × breadth ×height

step 1 : calculate the first one

v= 15cm ×8cm× 5cm = 1200cm^3

step 2 calculate the 2nd one

v= 15cm ×10cm×8cm = 600cm^3

number of bricks

1200cm^3 × 1bricks/ 600cm^3 = 2 bricks

Step-by-step explanation:

step 1. ABCD is an isosceles trapezoid because AD and BC are parallel, AB and CD are congruent

step 2. x = 56° (definition of an isosceles trapezoid)

step 3. x + y + z + 56 = 360 (definition of a quadrilateral)

step 4. y = z (definition of an isosceles trapezoid)

step 5. 56 + 2y + 56 = 360

step 6. 2y = 248

step 7. y = 124°, z = 124°.
