My dad has 8 oak and maple boards from the lumber yard. Each oak board is 9 centimeters thick. Each maple board is 6 centimeters thick. When my dad stacks the boards, the stack is 60 centimeters thick. How many of each type of board does he have
he has 4 oaks because each oak is 9 cm and 9*4=36 and he has 4 maple because the maple is 6 cm and 6*4= 24 and 24+36=60 so he as 4 of each if i am wrong i am sorry
