If there are 556 students in a school and each student needs to be given 5 pencils for a term, how many pencils are needed in total for a session (3 terms)? _______

Answer explanation

To find the total number of pencils needed for a term, multiply the number of students (556) by the number of pencils each student receives (5). So, 556 x 5 = 2,780 pencils are needed for a term. For a session(3 terms), multiply the total pencils needed for a term (2,780) by 3 (terms): 2,780 * 3 = 8,340 pencils are needed for a session (3 terms).
