You can put this solution on YOUR website! .
From one side, a plot is required to solve the problem.
From the other side, an access to the plot requires an Username and a Password, but I do not want to know these secrets . . .
General instruction: from the volume of the larger prism subtract the volumes of the two cutouts, that are the prisms, too.
After giving you a general instruction, the tutors' participation is not required, since the solution is EXTREMELY simple . . .
Making calculations is the students' honor duty and a privilege.
Happy calculations !
