Answer:

880 in³

Step-by-step explanation:

L = 20, W = 10, H = 8

2(h × W) + 2(h × L) + 2(W × L)

= 2(8*10) + 2(8*20) + 2(10*20)

= 2(80) + 2(160) + 2(200)

= 160 + 320 + 400

= 880 in³

Find the area of the shaded region of the square.
marishachu [46]

Answer:

42cm^{2}

Step-by-step explanation:

area of the square=14*14(l*w)

                              =196 cm^{2}

radius=14/2

         =7 cm

area of the circle=\pi r^{2}

                           =\frac{22}{7}*7*7

                          =154 cm^{2}

area of the shaded part =196-154

                                        = 42cm^{2}
