Li Gang has to pay 6.5438+0.9 million yuan to buy a house with one room and one living room, and his deposit is only enough to pay 40% of the house purchase price. The rest was lent to a bank 1 year, and the principal and interest were repaid in one lump sum after maturity, so Li Gang lent it to a bank at an annual interest rate of 5%, but the bank implemented the policy of directly deducting 1 year interest from the loan. Do you think this practice of banks is fair to customers? How much should Li Gang borrow from the bank if he wants to get the price difference?

It's not fair. (Contradicting the one-time repayment of principal and interest after maturity, if the customer loans 1 1.4 million yuan, it is not enough to buy a house. If he borrows more, he will pay more interest. )

According to the one-time repayment of principal and interest after maturity,190,000 x 40% = 76,000, the difference is 1 1.4 million, and the total principal and interest is1.4 million (65438+5%) =/kloc-0.

Borrow 1.2 million, down payment 7. 60,000 yuan, loan1.20,000, interest deducted first,1.20,000 * 5% = 0.60,000 yuan, and the remaining1.40,000 yuan, plus 7.6 is exactly1.90,000 yuan. The total amount of debt service is 6,543,800+0.26 million.

After sawing a cube into two identical cuboids, the surface area of each cuboid is 32 square centimeters smaller than that of the original cube, and the volume of the original cube is calculated.

Explain that one side of the cube is 16 cm, indicating that the side length of the cube is 4 cm.

32/2= 16 (cm)

The volume is: 4*4*4

= 16*4

=64 (cubic centimeter)

A: The volume of the original cube is 64 cubic centimeters.
