Answer:

2646 cm³

Step-by-step explanation:

To calculate the volume (V) of a cuboid use

V = lbh ( l is length, b is breadth and h is height )

here l = 21, b = 14 and h = 9, thus

V = 21 × 14 × 9 = 2646 cm³

Answer:

2646~cm^{3}

Step-by-step explanation:

There isn't really much to do here. To find the volume we multiply the three sides, which are already given to us (21, 14, 9) and just like that, we will get the volume of our cuboid.

Hope it helped,

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
