The path of the ball is the diagonal of the rectangle.
You can use the Pythagorean theorem.

a^2 + b^2 = c^2

64^2 + 48^2 = c^2

A drawing has a scale of 1:40.
uranmaximum [27]

Answer:

300,000 cm^{2} is bigger

Step-by-step explanation:

10 x 40 = 400

18 x 40 = 720

400 x 720 = 288,000 cm^{2} (area of the bedroom)

300,000 cm^{2} is bigger by 12,000 cm^{2} (so the kitchen is bigger)

Find the surface area of the composite figure. 6cm 5 cm 20cm 4cm 12cm 6cm​
Crazy boy [7]

Answer:

644 cm²

Step-by-step explanation:

Surface area of the composite figure = surface area of the large rectangular prism + surface area of the small rectangular prism - 2(area of the surface of the small rectangular prism that joins the larger prism)

✔️Surface area of the large rectangular prism = 2(LW + LH + WH)

L = 6 cm

W = 5 cm

H = 20 cm

Surface area = 2(6*5 + 6*20 + 5*20)

= 500 cm²

✔️Surface area of the small rectangular prism = 2(LW + LH + WH)

L = 6 cm

W = 4 cm

H = 12 cm

Surface area = 2(6*4 + 6*12 + 4*12)

= 288 cm²

✔️area of the surface of the small rectangular prism that joins the larger prism = L*W

L = 12 cm

W = 6 cm

Area = 12*6

= 72 cm²

✅Surface area of the composite figure = 500 + 288 - 2(72)

= 644 cm²
