A rectangular brick has a length of 5 centimeters, a width of 9 centimeters and a height of 20 centimeters.What is the surface a
a_sh-v [17]
ANSWER
The surface area of the brick is;

650 \: {cm}^{2}

EXPLANATION

The dimensions of the rectangular brick are

l = 5cm
w = 9cm
h = 20cm

The total surface area of a rectangular brick is given by,

T.S.A = 2(lw + lh + hw)

We substitute the values into the formula to obtain,

T.S.A = 2(5 \times 9 + 5 \times 20 + 9 \times 20)

T.S.A = 2(45+ 100+ 180)

T.S.A = 2(325)

T.S.A =650 \: {cm}^{2}

5. no because each spinner is not the same size. it's not divided equally. 6. yes because a cube has 6 faces, so 1 on each is even. 7a. 12% 8. the bag with 25 tiles has a 40% chance of blue tiles and the bag with 250 tiles has a 30% chance, so the chances of picking a blue tile from the 250 tile bag is lower
