What is a surface area of the cuboid with 4,5 and 9

Mathematics
1 answer:
Anettt [7]2 years ago
8 0

Answer:

SA = 202

Step-by-step explanation:

Surface area = Sum of all 6 areas of each side of the cuboid

SA = 2 (4·5 + 5·9 +9·4), because there are 2 of each kind of sides

SA = 2 (20+ 45 + 36)

SA = 2·101

SA = 202

cho tứ giác ABCD. Gọi M,N,P,Q là trung điểm của các cạnh AB, CD, AD, BC. Chứng minh rằng vecto MP = vecto QN, vecto MQ = vecto P
Dmitriy789 [7]

Answer:

Step-by-step explanation:

Xét tam giác DAB có: P là trung điểm AD, M là trung điểm AB

=> MP là đường trung bình của tam giác DAB => MP//BD và MP=\frac{1}{2}BD  (1)

Xét tam giác DBC có: N là trung điểm DC, Q là trung điểm BC

=> QN là đường trung bình của tam giác DBC => QN//BD và QN=\frac{1}{2}BD  (2)

Từ (1) và (2) => vecto MP song song cùng chiều với vecto QN

và độ dài MP = độ dài QN = \frac{1}{2}BD

=> vecto MP = vecto QN

Tương tự xét các tam giác DAC và tam giác ABC => vecto MQ = vecto PN
