I give 20! Find the surface area. And without explanation please, I don’t have enough time.
oee [108]

Answer:

816 cm²

Step-by-step explanation:

Surface area of the composite figure = (surface area of the larger rectangular prism + surface area of the smaller rectangular prism) - area of the side of the smaller rectangular prism that is joined to the bigger prism.

✔️Surface area of the larger rectangular prism:

Area = L*W*H = 20*5*6 = 600 cm²

✔️surface area of the smaller rectangular prism:

Area = L*W*H = 12*4*6 = 288 cm²

✔️area of the side of the smaller rectangular prism that is joined to the bigger prism.

Area = L*W = 12*6 = 72 cm²

Surface area of the composite = (600 + 288) - 72 = 888 - 72 = 816 cm².

lakkis [162]
50\times\frac{26}{100}\\\\=\frac{50\times26}{100}\\\\=\frac{1300}{100}\\\\=13\\\\50-13={\boxed{ \bf 37}}

50 points decreased by 26% is 37 points.

50\times\frac{26}{100}\\\\= 50 \times 0.26\\\\=13\\\\ 50-13={\boxed{ \bf 37}}

50 points decreased by 26% is 37 points.
