um aluno dispõe de quatro folhas retangulares, todas de dimensões 10 cm por 23 cm, para recortar os
polígonos que serão utilizados como faces de uma pirâmide quadrangular regular. de uma dessas folhas, ele recortou
um quadrado de área máxima e, em seguida, uma das faces triangulares do restante da folha, também com área
máxima. as demais faces laterais foram recortadas das outras três folhas disponíveis. em seguida montou a pirâmide
fixando esses polígonos com fita adesiva sem afetar a superfície dos polígonos recortados.
a) calcule o volume, em centímetros cúbicos, dessa pirâmide.
b) determine a medida da área, em centímetros quadrados, do papel que sobrou das folhas utilizadas após os
recortes.
